Internal Address
0 to 65535 (for bit-level addressing)
or
0 to 4999 (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.
