• The RnCPU and RnENCPU with firmware version "12" or later support these instructions. (Use an engineering tool with version "1.015R" or later.)
• The RnPCPU (process) with firmware version "03" or later supports these instructions. (Use an engineering tool with version "1.020W" or later.)
• LD: Normally open contact, LDI: Normally closed contact
These instructions output the status (active or inactive) of the specified block as the operation result.
• AND: Normally open contact series connection, ANI: Normally closed contact series connection
