CR#16: Connection status of the RTU mapping slave

Explanations:

b3~b0 display the connection status of RTU slave. The connection may encounter some problems when any of the bits

becomes 0. Firmware V2.0 and later versions support RTU mapping.

b0: Status of RTU slave 1

b1: Status of RTU slave 2

b2: Status of RTU slave 3

b3: Status of RTU slave 4

4.3 Numbering of Left-Side Modules

After DVPEN01-SL is installed properly, you need to compile the PLC program to control the special I/O module. PLC

offers FROM instruction (for reading) and TO instruction (for writing) to control the control registers (CR) in the special

I/O module.

Numbering of the modules: Every special I/O module connected to PLC MPU has a No. to allow you to know which

module is which when compiling the PLC program. The first special I/O module attached at the left hand side of the

PLC MPU is numbered as K100, the second as K101, the third K102, and so on.

5 Setting the Software

This section gives instructions on how to set DVPEN01-SL by DCISoft and explanations on each setup page. Before

you start a setup page, you have to select Ethernet in the Communication Setting window. Next, you can search by

IP address or use Auto-Search. You also can open the setup page for DVPEN01-SL by RS-232. DVPEN01-SL is set by

UDP port 20006; therefore, you have to be aware of the relevant settings of the firewall.
