The messages of the function block are sent to markers.
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
Inputs
SH and SL: The upper and lower limit setpoints are set at function block
inputs SH and SL respectively.
SV: The start value is used to cause the function block to count from a
specified value (Offset).
You can assign the following operands to function block inputs SH, SL and
SV:
• 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.
