Summary
CDU protocol driver implements communication with any device using CDU protocol on TCP/IP or serial networks. The communications blocks are dynamically created according the pooling cycle defined on the AccessType for each Device Point.
Communication Driver Information | |
|---|---|
Driver name | CDU |
Assembly Name | T.ProtocolDriver.CDU |
Assembly Version | 1.0.0.0 |
Available for Linux | False |
Devices supported | Any device compatible with CDU Protocol |
Protocol | Serial and TCP/IP |
PC Requirements | Ethernet port |
Configuration
Channels
Settings
Serial configures settings like BaudRate, Comm, and DataBits, while TCP does not require specific settings, but both require the following:
ServerMode: True
AcceptUnsolicited: True
ListeningPort: This port has to be different for each channel you create. For example. if you have 2 CDU channels, one has to be for example 502, and the other 503, as long as those ports are not being used.
Serial and MultiSerial channels, default configuration:
- BaudRate: 9600
- DataBits: 8
- StopBits: 1
- Parity: None
Nodes
Station Configuration
Serial channels:
- Nothing
TCP/IP channels:
- Station syntax: <IP address> ; <Port number>
Where :
- <IP address> = IP address of the slave device in the ASCII network
- <Port number> = TCP port where the slave device is listening (default is 502)
E.g.: 192.168.1.101 ; 502
Points
The syntax for the ASCII communication points is: <SequenceId>:<SizeOf>
Where:
- <SequenceId> indicates the data order where the TX message will be created:
- <SizeOf> indicates the characters amount from the configured tag
Usually is used as “0:46”, so it will starts to read in index 0, and read 46 char, this is, the whole message.
Access Point
Not necessary to do any setting.
Usage
How to use CDU in the equipment?
When you want to move in the menu, you just have to write the ASCII value below in the tag. In summary, if you want the action of “Pushbutton”, you write the “Ascii Value”.
Pushbutton | Dec Value | Ascii Value | Hex Value | Data Sent to PLC |

Up | 65 | A | 41 | 1b 5b 41 |
Down | 66 | B | 42 | 1b 5b 42 |
Right | 67 | C | 43 | 1b 5b 43 |
