RTCC LED lighting controllers - User Manual
In this example, three product triggers were received. The camera was
triggered using OP1.
An Ethernet message with tag number 10 was sent to the host computer
when the first trigger was received, but a reply was not received, so the
product was rejected for fail-safe operation.
After the second trigger, a Tag 11 message was sent, with the reply
'SN2,11,1'(OP2, tag 11, pass), so the reject pulse on OP2 was cancelled.
After the third trigger a Tag 12 messages was sent, with the reply
'SN2,12,0' (OP2, tag 12, fail), so the reject pulse on OP2 was not
cancelled.

Resync and FIFO mode
This example uses the same situation as the previous example, but the
products are 4 seconds apart, so that when a product is detected, there
are already two others travelling towards the reject gate.
Image processing software processes the image (which can take a
variable length of time), and then sends a pass/fail message to the TR-HT.
The pass/fail is re-synchronised to the original product presence and the
reject gate is opened if necessary. The configuration details for this are
shown below:
