1. Function code 03 (16#03): the PLC reads the data from several bit devices that are not discrete input devices
(eight pieces of data is read in this example). For function code 04, the operation is the same as for function code
03.
2. AS Series CPU module is connected to the DVP-ES2 Series PLC.
When SM96 and X0.0 are on, the AS Series CPU module sends and receives D32–D39 from the DVP-ES2.
