(3) Script File replacement
Q24DHCCPU-V/-VG cannot register/add login user(s) by using script file.
Register login user(s) in Setting/monitoring tools for the C Controller module.
(4) Verification of C Controller system after replacement
Replacement of Q12DCCPU-V (Basic mode) with Q24DHCCPU-V/-VG affects the operations of the C Controller
system as follows. Thorough review and verification is needed after replacement.
• The number of occupied slots are changed from 1 to 3, so the installation positions of I/O module and
intelligent function module, and start XY numbers are changed.
• Due to the change of C Controller module processing performance, the Q12DCCPU-V device and operation
timing are changed.
