4.2.3 Setting
This file consists of text characters. Editing can be done with “Notepad” software, but “MS-Excel”
software is recommended. The edited file should be saved with “CSV” as an extension.
Each line has meaning in the map file. A line beginning with character # is interpreted as a mean-
ingful line.
And a comment line does not begin with character “# “.
NOTE
Comment lines must not include the # character, otherwise ASGW may not work properly.
#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 specifies the holding time of the variable data bits. This t is the time (sec) to hold.
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.
#TCP_TIMEOUT, t
This specifies time-out value of Modbus TCP. This t is the time-out value (sec).
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.
#TSET, StnID
Writing in address 00001 of the coil in the Modbus address table carries out time setting in all
devices that have a time setting function. If StnID is set to 255 in the #TSET line, time setting
is carried out for all devices; if StnID is set to any number from 1 to 254, the setting is effec-
tive only for a specified device.
l Specifying analyzers and PCASs
Up to 31 analyzers and PCASs can be specified to be connected.
A unique StnID number must be allocated to each analyzer and PCAS. This StnID is key data on
Modbus interface.
Format = “#STN, StnID, StnType, IP_Address”
#STN Key word. The line start from “#STN” is recognized as one for specifying analyzers.
StnID ID number of analyzer (1-254)
StnType Type: GC8000/GC1000/ASIU/GCIU/PCAS
IP_Address IP address of analyzer
Example “#STN, 3, GC1000, 192.168.0.1”
