Ethernet Communication Module DVPEN01-SL

CR#251: Error Code

Explanations:

Table of error code:

	Bit No.	Error
	b0	The network is not yet connected.

	b1	Incorrect IP setting

	b2	CR#13 is set as “transmitting data”, but the data exchange
	b2	is forbidden.
		is forbidden.
	b3	CR#13 is set as “transmitting data”, but the data exchange
	b3	mode has not yet been enabled.
		mode has not yet been enabled.
	b4	NTP-Server connection fails.

	b7	SMTP-Server connection fails.

	b8	DHCP has not obtained the correct network parameter.

RTU Mapping

CR#15: Enabling Flag for RTU Mapping

Explanations:

1: Enable; 0: Disable. Default = 0

Firmware V2.0 and later versions support RTU mapping.

CR#16: Connection Status of 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

4.3Numbering 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.
