Inputs
The function block inputs >SH, >SL and >SV 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>
The actual value …QV> can be assigned the following operands:
• Markers MD, MW, MB
• Analog output QA01
Displaying the Parameter Set in the PARAMETERS Menu
• + Access enabled
• - Access disabled
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.
