MES INTERFACE FUNCTION CONFIGURATION TOOL
(6) Precautions on [Access target CPU settings]
(a) The MES interface module prepares for communication with the access target
(b) Be sure to set a correct series for [PLC series].
(c) When accessing the Redundant CPU, pay attention to the following points.
CPU when executing [Update settings], powering ON the system from OFF, or
resetting the programmable controller CPU.
Therefore, if a large number of access target CPUs are set, several minutes are
required for the preparation.
Confirm that [Update settings] is completed, or the MES interface module is ready
(X0 is ON.) before making access from the personal computer to the MES
interface module.
If [PLC series] is incorrectly set, either of the following will occur.
• At startup of the MES interface module, an error may occur in a
programmable controller CPU or a module on the route to the access target
CPU.
• The system may operate within the device range of the incorrect [PLC series]
setting.
• When the MES interface module is mounted to the Redundant CPU, it can
access the CPU of host station only.
It cannot access the CPU of other station.
• When the MES interface module is mounted to other than the Redundant
CPU, it cannot access the Redundant CPU of other station.
