We have one mobile device which is connected Ignition by Edge connection for using Modbus driver.
Basically it is working really nicely but we have found that when we power down mobile device for few minutes Ignition does not restart communication. When making “fast” <2 min power loss communication comes back nicely.
We got error message every 30 second in Console where is increasing read request key number.
Here is error message:
Read request with key “64” failed due to timeout. // 64 is number which is increasing by two for each errors
If we go gateway configuration and disable/enable device , communication comes back right away.
Also changing something on modbus device configuration fields and saving changes makes things work.
This is quite nasty problem because this makes our mobile device datalogging unstable.
I have not seen this problem before never even we have made lot of testing with modbus in Ignition
We are using Ignition 7.2.3 (b6630)
