11-3-4 Contact Operation Monitor
Description
The number of times each input contact or output contact is turned ON can be
counted (resolution: 50 Hz max.) and stored in Slave Unit memory. (This data
can be read using the CX-Integrator or using explicit messages.)
A monitor value can be stored in the Slave Unit memory so once the number
of contact operations reaches the monitor value, a flag in a status area in the
Slave Unit turns ON to notify the Master Unit. The notification details can be
read using the CX-Integrator or using explicit messages.
• No. of times measured: 0 to 4,294,967,295
(Stored data: 0000 0000 to FFFF FFFF hex)
• Measurement unit: No. of operations
Note (1) The contact operation monitor and the total ON time monitor cannot be
used for the same contact at the same time. Select only one of these
functions under the
Detection Mode .
(2) This function does not operate if the I/O power is not turned ON.
