The CAN receive function blocks for the JS6000 & JS7000 have two signals TimeOutBJM and TimeOutEJM.
The user manual for the CAN function blocks state that these signals indicate if the function block receives the respective messages within a 100ms timeout limit (T = Message not received within 100ms limit, F = Message received within 100ms limit).
I am having an issue with these blocks as both are not indicating the timeout unless they have received at least one message. Is anyone else seeing this?
