Connectivity to the ASCO 5210 Digital Power Meter via Modbus
This design specification describes the Modbus
communications protocol as supported by the Power Meter
5210. It includes instructions on how to pass information
into and out of the device via the Modbus network. This
publication should be used by individuals wishing to
integrate either device into their facility by developing
software to communicate with either device. Additional
information can be found in Power Meter Operator’s
Manual 381333-368.
Modbus Protocol
Implementation Basics
The following rules define the Modbus slave
implementation of the devices:
 The devices operate as slaves only
(communication must be initiated by the master).
 The maximum number of bytes contained within one
packet of communications is 64.
 The maximum number of registered accessed with
one read is 29.
the network will act on the command, but it will not
issue any responses.
Function Code Field. This is a second byte of each
transmission and represents the commanded action to the
slave device (for queries from the master) or the action that
was taken by the slave device (for responses from the
slave). Codes between 1 and 127 are defined as Modbus
RTU functions. The function codes supported by the
Power Meter are detailed on pages 4-6 .
Data Field. The data field varies in length depending on
whether the message is a request or a response packet.
This field typically contains information required by the
slave device to perform the command specified in a
request packet or data being passed back by the slave
device in a response packet.
Error Check Field. The error check field consists of a
16 bit (2 byte) Cyclical Redundancy Check (CRC16). It
allows the receiving device to detect a packet that has been
corrupted with transmission errors. Refer to CRC-16
Algorithm on page 2 for details.
Packet Framing and Timing
Transmission Format
Although the Modbus protocol supports both ASCII and
RTU modes of transmission, only the RTU mode is
implemented. Within the RTU mode, the ASCO devices
support the following communication parameters:
 8 data bits
 no parity
 1 stop bit
Modbus RTU Packet Format
Every Modbus Packet consists of the following fields:




Device Address Field
Function Code Field
Data Field
Error Check Field
Because the Modbus RTU protocol does not define any
explicit packet synchronization bytes, synchronization is
accomplished implicitly with the use of silent intervals.
According to the Modbus RTU standard, all messages
must start with a silent interval of at least 3.5 character
times. This means that every byte within a packet must
precede the previous byte by fewer than 3.5 character
times based on the baud rate. And every new packet of
data must begin at least 3.5 character times or more after
the packet that had preceded it.
In summary, the three timing intervals associated with the
ASCO devices are as follows:
 Maximum time between two consecutive bytes
within a packet < 3.5 character times.
 Minimum time between two consecutive packets is
> 3.5 character times.
Device Address Field. This is the first byte of each
Modbus RTU transmission. The device address is a
number limited to the range of 0 - 247 and is
associated with a single device configured with a
matching address. Only the slave device whose
address matches the value in this field will respond to
the specified command. Device address 0 indicates a
broadcast command. This means that every slave on
 Maximum response time from a Master request to a
slave response is < 100 milliseconds.

CRC-16 Algorithm
Procedure. The algorithm essentially treats the entire
data packet (less the start, stop, and, if used, parity bits) as
one continuous binary number. Since we are doing a 16-bit
CRC calculation, the binary number (entire packet) is
multiplied by 216 and then divided by the generator
polynomial. In the case of the Modbus protocol, the
generator polynomial is x16 + x15 + x2 + 1. The 16-bit
remainder of the division, which is the 16-bit CRC
checksum, is then appended to the end of the packet. The
resulting data packet including the 16-bit CRC checksum,
when divided by the same Generator Polynomial at the
receiver, will give a zero remainder if no transmission
errors have occurred.
1. Initially, load the 16-bit CRC register with the value
FFFF hex.
2. Exclusive OR the 16-bit CRC register with the first data
byte of the packet and store the result in the 16-bit CRC
register.
3. If the Least Significant Bit (LSB) of the 16-bit CRC
register is equal to one, then shift the 16-bit CRC
register to the right by one bit and then Exclusive OR
the result with the generator polynomial, A001 hex.
Otherwise, just shift the 16-bit CRC register to the right
by one bit.
4. Repeat step 3 until eight right shifts have been
performed.
The binary value of the Generator Polynomial is A001
hex. This is obtained by first dropping the mostsignificant-bit of the polynomial and then reversing the bit
order. This yields 1010000000000001 or A001h.
5. Exclusive OR the 16-bit CRC register with the next data
byte of the packet.
The steps for generating the 16-bit CRC checksum are as
follows:
7. The 16-bit CRC register contains the new checksum to
be appended to the end of the packet, Least Significant
Byte first.
6. Repeat steps 3-5 until all the bytes of the data packet
have been used in step 5.
CRC-16 Pseudocode. Below is the pseudocode for generating the 16-bit CRC checksum. XOR is the Exclusive-OR
function:
CRC16REG = FFFF hex
GENPOLY = A001 hex
FOR X = 1 to number of bytes in packet
BEGIN
XOR CRC16REG with the Xth data byte
FOR Y = 1 to 8
BEGIN
IF [(the least-significant-bit of CRC16REG) = 1] THEN
SHIFT CRC16REG one bit to the RIGHT
XOR CRC16REG with GENPOLY
OTHERWISE
SHIFT CRC16REG one bit to the RIGHT
END
NEXT Y
END
NEXT X
The resulting CRC16REG contains the 16-bit CRC checksum
CRC-16 C Programming Language Example. CRC16_checksum is a C language function that calculates and
returns the 16-bit CRC checksum of a string of characters. This is the brute force method as it consumes a lot of
processing power performing numerous bit shifts. A table look-up method based on this function would be more suitable
for embedded systems where processing power is at a premium. The following four parameters are passed as part of the
function
1. pointer to string
2. length of string (in bytes)
3. initial CRC value
4. desired Generator polynomial

The following C-language type definitions (typedef’s) are assumed:
1. typedef unsigned int uint;
2. typedef unsigned char uchar;
The function is defined as follows:
uint CRC16_checksum(uchar *Buffer, uint Length, uint CRC, uint Genpoly) {
uint index;
While (Length--) {
/* for each data byte in string */
CRC = CRC ^ (uint) *Buffer++;
/* exclusive OR data byte */
For (index = 0; index < 8; index++) {
/* for each of the 8 bits */
If ((CRC & 0x0001) == 1) CRC = (CRC >> 1) ^ Genpoly;
Else (CRC = CRC >> 1);
} /* for statement */
} /* while statement */
}
return(CRC);
An ASCO Example. Let’s assume the transmitting device desired to send the ASCII string “ASCO”. Using an ASCII
character look-up table, we have the following hexadecimal codes for each of the ASCO letters:
A = 0x65
S = 0x83
C = 0x67
O = 0x79
The transmitter would determine the 16-bit CRC checksum as follows (in C, both methods are equivalent):
CRC16_checksum(“ASCO”, 4, 0xFFFF, 0xA001) which returns CRC = 0xCD94
CRC16_checksum(“\x65\x83\x67\x79”, 4, 0xFFFF, 0xA001) which returns CRC = 0xCD94
Before sending the string, the transmitter would append the CRC checksum (in byte reverse order) to the string as follows:
“ASCO\x94\xCD” or the equivalent in hexadecimal notation “\x65\x83\x67\x79\x94\xCD”
If the receiving device received the string without any transmission errors, then doing the 16-bit CRC checksum on the
entire received string would yield (again, both methods are equivalent):
CRC16_checksum(“ASCO\x94\xCD”, 4, 0xFFFF, 0xA001) which returns CRC = 0x0000
CRC16_checksum(“\x65\x83\x67\x79\x94\xCD”, 4, 0xFFFF, 0xA001) which returns CRC = 0x0000
Since the CRC checksum is equal to zero, the transmission is deemed valid.
Had an error been induced during the transmission, such as the ASCII character ‘A’ being inadvertently changed to the
character ‘B’ (which is hexadecimal 0x66), the receiving device would determine the new checksum as:
CRC16_checksum(“BSCO\x94\xCD”, 4, 0xFFFF, 0xA001) which returns CRC = 0x3300
CRC16_checksum(“\x66\x83\x67\x79\x94\xCD”, 4, 0xFFFF, 0xA001) which returns CRC = 0x3300
Since the CRC is NON-ZERO (0x3300), the receiver would assume an error had occurred and discard the packet.

Note 4- Source Mode – Holding Register no. 40201
The source mode register defines the source bus to which
the Power Meter is connected. The Energy register display
window changes according to the bus defined. The user
can specify a normal bus connection, an emergency bus
connection, a connection to the load side of the bus or no
specific designation.

OTHER
Normal power bus
Emergency power bus
Load power bus
Any power bus with no
designation on the Energy
registers
When the LOAD selection is chosen, the Power Meter uses
the N/E INPUT status input to determine ATS switch
position. Two sets of Energy registers are used; Normal
energy registers & Emergency energy registers.
0-Normal
1 to 15-Failed
Note 5- Potential Transformer Ratio –
Register no. 40202
This register defines the full-scale voltage input value for
the three phases of voltage. This is based on the ratio of the
external voltage transformers (PTs) connected between the
Power Meter and the power bus.
Range
120 to 28,200
The value of 28,200 is the ratio 235:1 (120 * 235 =
28,200). Note that if external voltage transformers are not
required and subsequently not used, the ratio should be set
to 120, which is 1:1.
