Use the Micro810 Smart
Relay Functionality The Micro810 12-point (8 Inputs and 4 Outputs) controller comes with a built-
in smart relay function that can be configured using the optional LCD Display
and push buttons to control four relay outputs (O00…O03), without using any
software.
Each smart relay block controls one relay output and can be configured using one
of the following instructions:
• TON – On-delay Timing
• TOF – Off-delay Timing
• DOY – Turning on an output if the value of real-time clock is in the range
of Year Time setting.
• TOW – Turning on an output if the value of real-time clock is in the range
of Day Time setting.
• CTU – Count Up
• CTD – Count Down
• TONOF – On-delay timing on a true rung, and then Off-delay timing on
the false rung.
• TP – Pulse Timing
Smart Relay Block Execution Order
The smart relay block that is configured to control output 00 executes first,
followed by the smart relay block for output01, then output 02, with the smart
relay block for output 03 as the last to execute.
For example, if TON is configured to control O00, CTU for O01, TOW for
O02, and another CTU for O03, the execution sequence for the smart relay
instructions is TON (O00)
→
CTU (O01)
→
TOW (O02)
→
CTU (O03).
The default configuration is as follows:
TON for Output 00
CTU for Output 01
TOW for Output 02
DOY for Output 03
