Maximum Update Cycle of Detection level Data
The following tables list the maximum values for the update cycle of the detection level
monitoring when the Unit is operating with remote I/O communications in 2-channel
mode with the detection level monitoring mode (SW1 =OFF, SW2 = ON).
The maximum update cycle of the detection level monitoring depends on whether
Explicit messages are used and on the number of Sensors connected, as shown in the
tables below.
• When using Explicit Messages
Explicit messages are also used when a configurator is connected.
• When not using Explicit Messages
Normally, the update cycle of the detection level is much shorter than the values listed in the tables
above. However, the update cycles can be extended with some timings. Consider the maximum
refresh cycle when designing the system.
