We are running into issues with catching the handshake consistently in our PLC. We are using transaction groups to gather machine data. Once we trigger the transaction group, I have selected the handshake option for success and failure within the transaction group. What seems to be happening is the PLC is only catching the handshake every 2-3 times. We fixed it by adding a timer. I couldn't find anything online about how long ignition will keep that bit high or who conditions are set for the handshake options within the transaction group.
Is the plc clearing the handshake bit itself anywhere in the logic?
It is not. Will the ignition handshake stay high until it's cleared?
The handshake in a transaction group is just a single write that fires off on success or failure. What happens to that tag afterwards is up to you.
