Section where detailed information is described
Processing details
Outputs the on/off information of the specified device as the operation result. (Normally open
contact operation start instruction)
Outputs the on/off information of the specified device as the operation result. (Normally closed
contact operation start instruction)
Performs an AND operation between the on/off information of the specified device and the previous
operation result, and output the operation result. (Normally open contact series connection
instruction)
Performs an AND operation between the on/off information of the specified device and the previous
operation result, and output the operation result. (Normally closed contact series connection
instruction)
Performs an OR operation between the on/off information of the specified device and the previous
operation result, and output the operation result. (Single normally open contact parallel connection
instruction)
Performs an OR operation between the on/off information of the specified device and the previous
operation result, and output the operation result. (Single normally closed contact parallel
connection instruction)
Processing details
