How to use Assemblies with Reset Protection
When the PLC determines that it has a valid connection to the ConveyLinx-ERSC Module in question and is ready for it to respond to output data being written by the PLC:
- Your PLC program needs to move the value in the Current Module Reset Counter register into the Set Module Reset Counter register
- When the ConveyLinx-ERSC Module detects that the value in Set Module Reset Counter register is equal to the value in the Current Module Reset Counter register; the ConveyLinx-ERSC Module will respond to data being written by the PLC to the remaining output assembly registers.
*Please note that when the value in Current Module Reset Counter register is not equal to the value in the Set Module Reset Counter register; the values in the Input registers will updated by the ConveyLinx-ERSC Module and will be valid in your PLC program. In this state, even though the PLC may be writing data to Output registers, the **ConveyLinx-ERSC Module* will ignore it*
*To make sure a given ZPA zone accumulates upon power up, use EasyRoll configuration tool software to set the zone to “Accumulate”. When set from EasyRoll, this setting will be retained in the flash memory of the ConveyLinx-ERSC Module so that the zone will initially accumulate if a load happens to be in the zone at the time of power up. Learn about Accumulate function in EasyRoll
*When a ZPA zone is commanded to accumulate with a PLC and you happen to connect to that ConveyLinx-ERSC Module with EasyRoll; the “Accumulate” switch icon on the main screen will visibly indicate that the zone is accumulated. This visible icon will look the same as if it was clicked ON from EasyRoll.
Keep in mind that a *PLC command to accumulate IS NOT retained upon power loss to the *ConveyLinx-ERSC Module**. Only if the “Accumulate” switch is toggled “ON” with the EasyRoll is the accumulate condition for the zone retained in flash memory for use upon power-up
