Modbus RTU/ASCII/TCP - READ

- With this plugin you can readout RS485 Modbus devices with methods RTU/ASCII/TCP
+

Modbus RTU / ASCII / TCP/IP - READ

+ With this plugin you can read from RS485 Modbus devices with methods RTU/ASCII/TCP

-

Functions of the READ plugin:

- Read Coil (Function 1)
- Read Discrete Input (Function 2)
- Read Holding Registers (Function 3)
- Read Input Registers (Function 4)
+

RTU

+ The serial binary communication protocol. It is the communication standard that
+ became widely used and all series of PLC's and other device producers support it.
+ It goes about the network protocol of the 1Master x nSlave type. The Slave devices can be 254 at the most.
+

ASCII

+ This protocol is similar to Modbus RTU, but the binary content is transformed to common ASCII characters.
+ It is not used as frequently as Modbus RTU.
+

RTU over TCP

+ Means a MODBUS RTU packet wrapped in a TCP packet. The message bytes are modified to add the 6 byte MBAP header and remove the two byte CRC. +

TCP/IP

+ It is a network protocol - classic Ethernet TCP/IP with the 10/100 Mbit/s speed rate, a standard net HW Ethernet card is sufficient.
+ The communication principle (1Master x nSlave) is the same as for Modbus RTU.

Supported data types:

- No conversion (passtrough) / BOOL / INT / UINT / FLOAT / STRING
