Heidenhain-Bit

The bit trigger triggers the data transfer when the assigned logical data point takes a value 1. If the assigned data point is not a logical data point, the trigger triggers when the data point takes a different value as NULL. You can also send a reply and a fault message to two additional data points if the transfer is incorrect.

Access data	Heidenhain connection which the relevant data point is reached.
Item	Heidenhain data point that triggers the transfer as soon as it assumes a value other than 0. Use the button “... ” to open the tag browser (see below) for the interactive selection of an item.
Reset bit	Resets the Heidenhain item to zero after the transfer. Should usually be disabled because a bit should only be written from one side. Instead, use the answer bit to tell the controller that the transfer has completed.
Answer bit active	Sends one bit to another data point in response that the transfer has completed.
Item	Heidenhain data point to which the response is sent. It must be a logical (bit) data point that has state “0” or “1”. Use the button “...” to open the tag browser (see below) for the interactive selection of an item.
Reset answer bit after	After the set time, the response bit is reset.
Error bit active	Sends a bit to another data point if the data transfer was faulty.
Item	Heidenhain item (bit) that is set with transfer errors. It must be a logical (bit) data point that has state “0” or “1”. Use the button “...” to open the tag browser (see below) for the interactive selection of an item.
Waiting for failing edge	If you don't want the OPC Router to trigger continuously when the bit is active, activate this checkbox. This causes the OPC Router to trigger only once when the bit is active and then wait for a "falling edge" before triggering again.
