b)
If TransTrigger = 0, then the triggering method is enabled, but no message will transmit.
RTA460 Display Data Example:
TIA Portal Example:
The data will still go to the RTA gateway, however the RTA gateway will
NOT transmit the data to the ASCII device until the Slot12[0] triggers the TransTrigger.
c)
If TransTrigger is between 1-65534
AND
the value
IS
equal to the TransHandshake diagnostic
variable, then no new message will transmit, until Slot 12[0] triggers again.
RTA460 Display Data Example:
d)
If TransTrigger is between 1-65534
AND
the value
IS NOT
equal to the TransHandshake
diagnostic variable, then a new message will be transmitted. The value in TransTrigger will then
be moved to TransHandshake.
TIA Portal Example:
Once the Slot12[0] increments (data is sent from the PLC to the ASCI
device) then the Slot2[0] will get updated with the handshake
