Run/stop commands can be sent from the CX-Process Tool to a Loop Controller
connected remotely.
Monitoring the
operation status
Check the following items before operating the Loop Controller.
• Make sure the Analog I/O Units used with the Loop Controller are properly
mounted.
• Make sure the unit numbers on the front panel of the Analog I/O Units coincide
with the unit numbers set in the Field Terminal Function Blocks. Data for anoth-
er Special I/O Unit will be read and written if an incorrect unit number is used.
• Make sure the initial settings in the System Common Block in the Loop Control-
ler are correct. Check that the DM Area words for the Node Terminal Function
Block in the CPU Unit of the Loop Control Unit will not be used for any other
purpose.
• When writing data to the I/O memory in the CPU Unit with function blocks (e.g.,
using Send All Blocks, Expanded DO/AO Terminal to CPU Unit, or DO/AO Ter-
minal to CPU Unit for a Loop Control Unit and using user link tables and the
HMI function for an LCBjj), be sure that the words written to in the I/O
memory are not being used for any other purpose. If I/O memory words are
allocated to more than one purpose, the PLC system may act unexpectedly
and cause injury.
