Date Code 20081022 Instruction Manual SEL-787 Relay
Modbus RTU Communications
Communications Protocol
To build the response, the device calculates the number of bytes required to
contain the number of bits requested. If the number of bits requested is not
evenly divisible by eight, the device adds one more byte to maintain the
balance of bits, padded by zeroes to make an even byte.
In each row, the input numbers are assigned from the right-most input to the
left-most input (i.e., Input 1 is TLED_06 and Input 8 is ENABLED). Input
addresses start at 0000 (i.e., Input 1 is located at Input Address 0000).
Table E.7 includes the coil address in decimal and lists all possible inputs
(Relay Word bits) available in the device. Note that the command depends on
the device hardware configuration; the device responds only to installed cards.
