(b) Two transmission methods of the monitoring results are available for the condition
agreement transmission for device monitoring. These include edge triggered
transmission and level triggered transmission.
• Edge triggered transmission
The monitoring conditions registered by the user (conditions for sending monitoring results), the monitoring
condition values and the monitoring information read from the programmable controller CPU are compared.
The monitoring results are sent or notified only once when an agreement of the monitoring conditions is
detected for the first time.
After that, when the monitoring information read from the programmable controller CPU does not match the
monitoring conditions and then it matches the monitoring conditions once again, the monitoring results are sent
or notified.
• Level triggered transmission
The monitoring conditions registered by the user (conditions for sending monitoring results), the monitoring
condition values and the monitoring information read from the programmable controller CPU are compared.
While the monitoring conditions agree, the monitoring results are sent or notified at each cycle time.
(Timing to transmit data)
(c) In the condition agreement transmission for device monitoring, the head device for
each block is the monitoring target for condition monitoring of each block device.
For the condition agreement transmission, 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 head device of each block using the following table.
