■Monitoring condition
In the condition match send for device monitoring, the start device for each block is the monitoring target for condition
monitoring of each block device.
For the condition match send, the monitoring conditions that can be designated for the device to be registered by the user and
the registration values when designating the monitoring condition are listed in the table below.
Register the monitoring conditions for the start device of each block using the following table.
Monitoring condition
Device value or status = device monitoring condition value or status
Device value or status  device monitoring condition value or status
Monitoring device  monitoring condition value
Unsigned
Monitoring device < monitoring condition value
Monitoring device  monitoring condition value
Monitoring device > monitoring condition value
Monitoring device  monitoring condition value
Signed
Monitoring device < monitoring condition value
Monitoring device  monitoring condition value
Monitoring device > monitoring condition value
■Monitoring condition value, status
In device monitoring, register the monitoring condition value or status for C24 to judge that the numeric value/status of the
monitoring device for condition match send (start device of each block) satisfy the condition with numeric values listed below.
Type of monitoring device
Bit device
Word device
Ex.
Condition satisfies when M0 = ON
Registration value for the monitoring condition: 0001H
Registration value for the monitoring condition value or status: 0001H
Ex.
Condition satisfies when D0 > 100 (signed)
Registration value for the monitoring condition: 000AH
Registration value for the monitoring condition value or status: 100 (64H)
In status monitoring for the CPU module, the monitoring conditions and condition values for condition match
send are not registered.
Instead, it is registered whether or not the status monitoring of CPU module will be performed.
Monitoring results in the condition match send are transmitted only once when an error is detected by the
status information read from the CPU module for the first time.
