Printed in USA
This specification defines the communications database for the Form 4C recloser
control. The database is accessed and operated upon by the communications protocol
defined in specification DATA002179 entitled “Cooper Power Systems Communication
Protocol”.
NOTE: The following definitions apply to the tables below
Scale Factor - This is the factor by which a signed integer value read from the
Form 4C control, is divided to get the value of the variable in the indicated units.
Function Code - This code is used to access the parameter through the front
panel of the F4C control, if applicable, and is listed for information only.
Cross-Reference - A Cross-Reference refers to the controls internal
database, and is listed for designer’s information only. This reference is not
useful to the user.

Control Setup
1.
Function Code 81 - Communications Port Baud Rate
Self-explanatory. The real-time port is capable of 300, 1200, 2400, 4800,
9600 and 19200 baud rates. Transmit speed always equals receive
speed. The baud rate "code" 1-6 must correspond to the baud rate of the
system.

Function Code 82 - Control Communications Address
This parameter sets the PG&E/2179 address for the Form 4C.
Range is 0 to 2046.
3.
Function Code 83 - Communications Port Handshake Mode
The transmit/receive handshake method is selectable to accommodate
different types of communication system interfaces. The Handshake
mode specifies the way that the output at pin (4) and the input at pins (7 &
8) of P-20 are applied in the communication scheme.
2
Mode 0 - No Handshaking. Pins 7/8, which are usually Request to Send, are ignored,
and Pin 4 usually Clear to Send is always low. This mode is only useful on a single
slave system.
Mode 1 - For Factory use only.
Mode 2 - Modem Control Mode, for controlling a modem or Fiber-Optic circuit board
where a transmit enable or "push-to-talk" signal is required. RTS is ignored. Pin-4,
in this case Transmit Enable, goes high for a period programmed by function code 85
before transmission of the reply begins. This allows for stabilization of transmitter
hardware before the message is actually sent. This signal remains high for 50
milliseconds after the reply is completed.
Mode 3 - This mode is the same as Mode-2, except that the signal remains high for 0
milliseconds after the reply is completed.
Mode 4 - This mode is the same as 2, except that the signal remains high for 10
milliseconds after the reply is completed.

Function Code 84 - Communications Port Sync Characters
Defines the period of time the receive must be idle to assume the start of a message.
A concept known as dead-line sync, is used to determine the start of the request
message. When used on a ring configured communication system, the control
"hears" request messages for devices at other nodes on the received data line.
Since the first part of a message is the address, the control can determine if the
message is intended for it, and ignore the remaining bytes if not. A period of time,
during which the received data line is idle, defines the end of the previous message.
This idle time is the deadline sync period. The control is now synchronized so that
the next byte received is considered the beginning of a new message.
The value programmed is the equivalent number of character periods that the receive
line must remain inactive to be considered the end of a message. The control will
determine the actual time delay internally, taking into account baud rate and the
number of bits in the character. The range is zero to 10 characters.
3
5.
Function Code 85 - Communications Port Transmit Enable Delay
As described in the section on handshaking modes, this parameter defines the delay
after the Transmit Enable signal on Pin 4 of P20 goes high before transmission of the
reply begins. This allows for stabilization of transmitter hardware before the
message is actually sent. The value entered specifies the number of milliseconds
that elapse before transmission begins, in a range of zero to 425. When the modem
interface is used, a delay of 50 milliseconds is suggested.
6. Function Code 86 - Clearing the Communications Port Time Tagged Buffer
There are three, independently clearable, time-tagged buffer pointers, they are:
1. the front panel keyboard (Code 161, scroll)
2. the data port (front panel DB9)
3. the Communications Port (internal Fiber-Optic port)
For “pre-Code 86 firmware” the Communications Port time-timed buffer can
clear only if the Supervisory Switch is ON (up)
For Firmware supporting Code 86, the SCADA port Time-Tagged buffer pointer can
clear only if all of the following are true:
1. The Form-4C has previously logged at least one event with Code 86 OFF
2. Code 86 is now ON; and Either
a) The Supervisory Switch is ON (up) and/or
b) Code 77 is 14 or higher

Exception and Error Handling
1)
If a remote receives a valid "broadcast" message, it executes the commanded
function but does not respond with a return message. Instead, the next time a
message is to be sent in response to a specific (non-broadcast) command, the
BAK bit (broadcast acknowledge) in that message is set.
2)
If a remote receives a message that contains its REMOTE address (multi-master
addressing is not supported), but has framing errors, is of incorrect length, or if
CRC fails to check, then no response is given. In the next message that the
remote sends to the master, the appropriate error code in the port status byte will
be set to indicate that an erroneous reception has previously occurred.
3)
If a remote receives a message that is addressed to it and is otherwise correct,
but contains an unrecognized function, command, sequence number, ordinal
type, or event type, then the remote responds with a nine-byte message which
echoes the function code, except with the NOP set. Unused bits of bit-oriented
commands such as "Basic Scan" are not ignored and will cause an error if
set/reset when not expected. If a select/operate or write/execute sequence had
been in process when the unrecognized message was received, then the
message will be considered an out-of-sequence message, and the sequence
will be reset and the RST will also be set in the response. The remote takes no
other action. Data will be placed in its error file that indicates what error has
occurred. In the next message(s) that the remote sends to the master, the ERR
bit in the RTU status byte will be set to warn the master to read the error file.
4)
If a remote receives an out-of-sequence message, it responds with a nine-byte
message, which echoes the function code except with the RST bit set. An
out-of-sequence message is any message requiring a prior "select" which has
not been received, or any message (other than the expected one) received while
a previously-started multiple-message sequence has not been completed. Data
will be placed in its error file, which indicates what error has occurred. In the next
message(s) that the remote sends to the master, the ERR bit in the RTU status
byte will be set to warn the master to read the error file.
5)
In the event that over-current protection action is required, normal Scan data and
ordinal writes may be inhibited (SBO is never inhibited). If the scan operation is
not allowed for approximately 5 seconds, a "timeout error" will be placed in the
error file. In the next message(s) that the remote sends to the master, the ERR
bit in the RTU status byte will be set to warn the master to read the error file.
6
6) In any case where the error file contains data, the error bit will be set and remain
set until the file is read. In the event that multiple errors occur, the most recent
information will overwrite previous data. After the master reads the error
information, the ERR bit in the RTU status byte will be reset, but the error file data
remains until cleared by a write sequence. The error file should be read and
cleared promptly to prevent the possibility of data corruption from overwriting.
7) If the control experiences a power on reset, the "RTU needs configuration" bit will
be set in the RTU status byte on subsequent messages. The bit is cleared
automatically by writing the scan table file (Ordinal 3). The real time clock should
also be set at this time.

SBO/Control Internal Parameter Modification
1.
2.
When changing values via communication, the 2179 protocol permits
writing up to 64 contiguous 2-byte ordinal parameters with a single
message. Here's the typical scenario:
a) The entire message is received from the master and checked for
communication errors.
b) Each parameter, in order, is checked for errors, (such as too high or low)
and if valid, is entered into the parameter table. If the parameter is not
valid, further message processing is halted, and an error (including
which parameter) is recorded in the error file (Ordinal 0).
c) Repeat step 2 until all components of the message are done or an error
is detected.
d) Reply message is built, and sent to master.
e) There will be a period that the control is operating with "mismatched"
information. This is no different, however, than entering a new control
configuration at the front panel one entry at a time. In either case, if many
changes need to be made while on line, caution regarding “intermediate
states” is warranted.
Special Cases
a) Parameters Changing in General
To maintain maximum communication channel bandwidth, messages
that take a "long" time to execute will require special provisions for
error handling. For these messages, when the remote receives a
properly formatted message with no CRC or other errors, it will
respond promptly with the normal response message, which indicates
to the master that the message was properly received and that
execution has been started. The remote will go ahead with execution
at its own pace, and assuming the execution is properly completed, no
other response will be made. If the command is found to be not
executable, then the remote will abort execution, and put data on its
error file that indicates what error has occurred. In the next
message(s) that the remote sends to the master, the ERR bit in the
RTU status byte will be set to warn the master to read the error file.
The error file provides the master a tool for optimizing
communications. When the Form 4C indicates the existence of an
error file, it does not require the master to read that file. Whether or not
the master reads the error file, the Form 4C will continue to respond
normally to all commands.
8
Remote communication is not available during parameter changing.
Examples:
1. Write Execute messages. This is a case where the command may be
PARTIALLY executed; that is the command executes until an error is detected
and then stops ALL further execution at that point. An error code indicating
"out-of-range" and the offset value that failed is placed in the error table.
2. Control operations which may inherently take a while to perform. A possible
error is a control or recloser failure that prevents operation. An error code for
"mechanism failure" is placed in the error table.
3. Parameters that require the cold start type update
a) The entire message is received from the master and checked for
communication errors.
b) Each parameter, in order, is checked for errors, (such as too high or low) and
if valid, is entered into the parameter table and the database is updated.
Should a parameter requiring cold start be encountered, the control software
will restart IMMEDIATELY. The remaining parameters from the message will
be discarded and NOT be changed. Also, no reply message is built or sent.
During the restart period the control is off-line for about 2-3 seconds, so
communication (and OCP) will not be available.
These parameters should be sent in a multi-parameter write unless they are
the final entry in the message. A safer technique would be to send individual
messages to change these values, then read back later to confirm their
change. There are 2 parameters in the F4C that require cold start update:
TCC Module Select ordinal 6-0000
Line Frequency Select ordinal 6-0002
4. Using the control Real-time Clock
a) When reading the clock, if the time has not been set, an error will be indicated
in the error file so that the master can be aware that the returned value is not
the correct time of day.
b) When setting the clock, the ordinal number for "Year" (6-82) must be set
separately. The control needs this information to take into account leap year
for proper computation of the Julian day.

INPUT SUBSYSTEM
2-Bit Status Change corresponds to what some other protocols call “Multiple
Change Detect” (or MCD bits). Each sequence 3x status point has a
corresponding change bit, that will assert if the sequence 3x status has changed AT
LEAST TWICE since the last 2-bit status response.
The data bytes are transmitted in the following order:
Sequence 00 (sequence 30 MCD bits 0-7, followed by sequence 30 bits 0-7)
Sequence 01 (sequence 30 MCD bits 8-15, followed by sequence 30 bits 8-15)
Sequence 02 (sequence 31 MCD bits 0-7, followed by sequence 31 bits 0-7)
Sequence 03 (sequence 31 MCD bits 8-15, followed by sequence 31 bits 8-15)
Etc…
Sequence numbers used in 2-bit STATUS CHANGE and SCAN-BY-TABLE operations.
