Application and Function

Power Supply Interruption

The following table shows reactions to the changes in operating voltage:

Voltage level

Reaction of the controller

 

 

19.3 to 28.8 VDC

Normal operation

 

 

< 18.0 VDC

Alarm state (internal variables are written and put to the inputs/

 

outputs).

 

 

< 12.0 VDC

Inputs and outputs are switched off.

 

 

If power supply is interrupted, all inputs and outputs discontinue and return to the off "safe" state.

Small System A Safety PLC can be reconfigured while the network is executing an existing Reconfiguration configuration. Resources which require configuration must be stopped. The following table describes the reconfiguration procedure:

Step

Action

1Using the XPSMFWIN programming environment, stop the Safety PLC’s system which requires the new configuration.

2Download the new configuration fully checked by a qualified safety engineer to the Safety PLC via Ethernet cable Cat 5, grade D or better.

3Once the module is re-programmed, start the device.

4Execute the new configuration immediately.

Large System Reconfiguration

The following table describes the reconfiguration procedure for large systems:

Step

Action

1Stop the relevant resources within the network using the XPSMFWIN programming environment. Small segments of a network can be reconfigured in stages.

2Connect your PC to any Ethernet communications point.

3Download the new configuration(s) fully checked by a qualified safety engineer to the Safety PLC network via Ethernet cable Cat 5, grade D or better.

4Restart all devices, preferably in stages - system by system.
