Delta DVP-ES3 — 6.19.2 Explanation of Communication Instructions

Chapter 6 Applied Instructions Example 6 1. Function code 10 (16#10): the PLC writes the states into several word devices. 2. ES3 Series CPU module is connected to the DVP-ES2 series PLC. 3. Suppose the values for D20–27 are listed in the following table (waiting to write data to the devices T0–7 of the DVP-ES2). 6_ When SM96 and M0 are ON, the PLC can write data to the T0–7 in the DVP-ES2 series PLC. The address of T0 is 16#0600. The following table lists the operands of the MODRW instruction.
