(6) Logging function
5000 data can be collected for each channel. The analysis of the collected data can improves maintainability of
the system used.
(7) Backup of a set value to a non-volatile memory
Initial settings in the buffer memory can be backed up to a non-volatile memory. Initial settings do not need to be
reset when the power supply is turned on or the CPU module is reset.
(8) Changeable slope of I/O conversion characteristics
A slope of I/O conversion characteristics can be changed by configuring the offset/gain settings.
(9) Easy setting with GX Works2
Sequence programming is reduced since initial settings or an auto refresh setting can be configured on the
screen. In addition, setting status and operating status of modules can be checked easily.
(10)Online module change
This module can be replaced without stopping the system.
(11)Reduced man-hours and costs (A signal converter is not needed.)
A CT can be connected to a programmable controller directory using a CT input module; as a result, a signal
converter installed outside is not required. Therefore man-hours and costs are reduced.
