6.11 Analog Input/Output Modules
RTU-EN01 offers control registers (CR) for analog I/O modules and is built-in with mapping tables of CR for
read/write. The user can check the CR to be read/written and use Delta’s communication module DVPEN01-SL to
map the CR directly to D registers in DVP-SV series PLC and read/write the D register through PLC program,
controlling the analog I/O module connected to RTU-EN01. RTU-EN01 supports maximum 64 data
reading/writing.
f This function works with DVPEN01-SL of firmware V2.0 or versions above.
