#SLAVE, n
This n is the Slave ID when DCS accesses to ASGW with Modbus interface and commonly
uses on the 2 communication ports. Range is 1 to 247.
#RETRY, m
This m is the number of retry times when a write error occurs. Range is 1 to 32767.
#TOUT, t
This t is character time-out in the communication between DCS and Modbus RTU. Adjust the
value depending on communication speed. Unit is ms [millisecond] and range is 10 to 5000.
#KEEP_BIT, t

This function can be used on Rev. 1.01.04 or later of ASGW. The default value is 5 sec, and
range is 0 to 3276.

This function can be used on Rev. 1.01.03 or later of ASGW. The default value is 30 sec, and
range is 1 to 100.
