ioLogik 2500 Series Offline Configuration Management

• Safe Mode Status

Enable Communication Watchdog for Safe Mode allows you to control how an AO channel acts

when the network is disconnected.

If the Communication Watchdog is enabled, a network disconnection will activate a safe state. The AO

channel can be configured to a defined value during the safe state.

NOTE

Since the ioLogik 2500 does not have AO channels, the AO

setting will only show up when the project

contains E1200 AO modules (such as the E1241).

Virtual Channel Setting

The ioLogik 2500 has 10 internal virtual channels to support front-end statistics functions.

The data source is the real I/O channel, such as AI and DI counters, some of which need to be converted to

the appropriate time unit. The operation is illustrated below.

NOTE

For AI/Counter scaling, configure Scaling on the AI or Counter Configuration panel before selecting

operations in the virtua

l channels.

For example, if you want to monitor the daily flow at a point in a pipeline, you can use a pulse output flow

meter, where 1 pulse indicates 5 ml. You can set the virtual channel’s scaling function so that 1 tick of

counter input equals 5 ml. Next, set the Accumulation flag, and configure the Time Interval to 24 hours.

This will set up the virtual channel to log the total water flow volume over a period of 24 hours.
