can have the following operands:

• Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04

IA01: terminal I7

IA02: terminal I8

IA03: terminal I11

IA04: terminal I12

• Analog output QA01
• Actual value

QV> of another function block

Actual Value

QV>

Contacts

• C 010F to C 320F: Actual value ≥ upper set point
• C 01FB to C 32FB: Actual value ≤ Lower set point value
• C 01ZE to C 32ZE: Actual value = zero
• C 01CY to C 32CY: Value range exceeded

Coils

• C 01C_ to C 32C_: counter coils, count with rising edge
• C 01D_ to C 32D_: count direction definition,

status 0 = count upwards, status 1 = count downwards

• C 01RE to C 32RE: Reset actual value to zero
• C 01SE to C 32SE: accept defined actual value with rising edge.

Memory Requirement of the Counter Relay

The counter relay function block requires 52 bytes of memory plus 4 bytes per
constant on the function block inputs.
