DVP-ES3 Series Programming Manual Example 1 1. Function code 01 (16#01): the PLC reads the data from several bit devices that are not discrete input devices (16 pieces of data is read in this example). For function code 02, the operation is the same as for function code 01. ES3 Series CPU module is connected to the DVP-ES2 Series PLC. When SM96 and M0 are on, the ES3 Series CPU sends and receives the Y0–Y17 commands from the DVP-ES2. _6 When the address of Y0 is 16#0500, the states of Y0–Y17 in DVP-ES2 are listed in the following table. The following table lists the operands for the MODRW instruction.
