1-4. PLC communication functions (OMRON CJ/CS
Series)
Configure the PLC communication settings of GD-70D-EA.
The settings can be configured by the following methods:
To flexibly set the small number of devices:
Use the Web screen of the authorized user mode.
Multiple items can flexibly be set through the Network screen of the Web function.
If not [PLC MODE] = 1, it is not possible to change all the items.
See 1-4-2, “Setting the communication with PLC through the Web function” for details of the setting
method.
To quickly set a large number of devices through the operation on the gas detector:
Use the GD-70D-EA front panel.
The setting can be easily configured using front panel keys in the following two items: [PLC MODE]
and [PLC AREA].
PLC IP address XXX. XXX. XXX.251 and NODE251 are fixed.
([xxx] is the same as the IP address of GD-70D-EA.)
See 1-4-3, “Setting the communication with PLC through the GD-70D-EA main unit” for details of the
setting method.
