Channels
This section allows you to add, delete or edit channels. All they can be monitored on monitoring
pages and their values can be recorded periodically by the data logger.
Up to 24 channels can be set up.
There are two types of channels – discrete (it forms by one digital input in OPEN/CLOSE mode)
and general (it forms by up to 2 primary parameters and constants)
It is important to know that for general channels, the sequence of operations is OP1, then OP2,
and finally OP3.
It is possible to use a digital input in OPEN/CLOSE mode to form a general channel. In this case,
its values for operations are 0 (for CLOSE) and 1 (for OPEN).
8.2.5.
Alarms
This section allows you to add, delete or edit alarms. Up to 24 alarms can be set up.
There are four types of alarms – Warning, Minor, Major and Critical.
Only channels can be used to form the alarms.
The alarms are independent but can be assigned to a channel. There isn’t a restriction to which
channel to assign the alarm.
For every alarm up to 2 conditions can be used. Both conditions can be logically joined using the
logical operators AND and OR.
It is not mandatory to use the same channel in both conditions. In this case, conditions for two
different channels can be combined in one alarm.
