Input
I1: When the function block is triggered, the value present at function block
input >I1 is temporarily stored and then transferred to the NET. The function
block input can be assigned the following operands:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
…
QV of a different function block.
PUT diagnostics
The PUT function block only functions if the NET is running properly
(
800 standard expanding”, page 325).
Function of the function block
When the trigger coil PT..T_ picks up, the contact PT..Q1 and stays closed for
as long as the trigger coil remains activated.
The pickup triggers the buffering of the input value present at input I1.
The function block then transfers this value to the NET. During this time, the
function block contact PT..Q1 closes.
If the temporarily stored value is not sent, the contact PT..E1 closes and
therefore indicates a transfer error. It stays closed until the trigger coil PT..T_
picks up to issue a new send job.
The signal diagram shows the relationship of the send job and its triggering
by the trigger coil:
