Internal Address
0 to 65535 (for bit-level addressing)
or
0 to 9999 (for word-level addressing)
This field specifies the database address in the module's internal database to use
as the destination for data brought in by a read command or as the source for
data to be sent out by a write command. The database address is interpreted as
a bit address or a 16-bit word (register) address, depending on the Modbus
Function Code used in the command.
For Modbus functions 1, 2, 5, and 15, this parameter is interpreted as a bit-
level address.
For Modbus functions 3, 4, 6, and 16, this parameter is interpreted as a word-
level or register-level address.
Poll Interval
0 to 65535
This parameter specifies the minimum interval between issuances of a command
during continuous command execution (Enable code of 1). The parameter is
entered in tenths of a second. Therefore, if a value of 100 is entered for a
command, the command executes no more frequently than every 10 seconds.
Reg Count
Regs: 1 to 125
Coils: 1 to 800
This parameter specifies the number of 16-bit registers or binary bits to be
transferred by the command.
Functions 5 and 6 ignore this field as they apply only to a single data point.
For functions 1, 2, and 15, this parameter sets the number of bits (inputs or
coils) to be transferred by the command.
For functions 3, 4, and 16, this parameter sets the number of registers to be
transferred by the command.
