Redundancy between two AXC-2152 and BK PN TPS
Hi, i've been working on a project with two AXC-2152 and 1 BK PN TPS.
To stablish a communication between the IO Controller (Primary AXC for example) and the IO Device, i need to do it using AR_MGT only?
I'm asking that because when i let the settings "Start AR on startup" = YES, i couldn't communicate correctly.
Comments
I've been doing the following treatment to start "AR" and "STOP" if the controller assume the primary role or not.
But after simulating some signal on my analog module, this behavior happens when the controllers switch roles.
I configurated my channels to "set zero in case of no communication". I don't want to change to "keep the last values" because to my process, in case of continous failure, hazardous situations may occur.
There is a PLCnext Store app that implements system redundancy:
It will probably be quite complex to reproduce the function of that app yourself, so I would recommend using the app.
I'm trying to test the app that you recommend me, but i couldn't see the usage of "AR_MGT" function block to start the "AR" between the PN Controller and PN Device since the parameter Start "AR" on startup is set as NO .
To solve this problem, the correct procedure to download the project to both controllers is:
Rebuild all -> download to primary controller -> Rebuild all again -> download to secondary controller.
