DVP-ES3 Series Programming Manual Note: Before the connection is established, it is suggested NOT to use data (RX/RY/RCR Read/RCR Write) in the mapping area. _2 21. You can set SM227 to ON and use SR1553, SR1554, SR1555 to check if the parameters of the extension module DI/DI and the number of the connected modules are correct, once the CPU is supplied with power. If the result is incorrect, the CPU stops running and store the error (16#1414) in SR180 and SM10 = ON. 22. SM228 and D2800 ~ D28079 When SM228 is ON, it is to disable the data exchange among the CPU and its connected modules.
When SM228 is OFF, data exchange among the CPU and its connected modules is enabled and data is stored in D2800 ~ D28079. If the PLC is connected with a special extension module, the PLC uses registers in D28000~D28079 and the registers in this area correspond to CRs to update data. If you need to use this area, you need to pay attention not to use the same area repetively. See the example below to learn how this works. 23.
