Serial Line Configuration Configure the Manager To configure the Modbus_Manager of your controller, proceed as follows: Step Action 1 Select the Configuration tab and double-click on the controller. 2 For the TM238LDD24DT and TM238LDA24DR: click the Communication → Serial Line entry on the left hand side. For the TM238LFDC24DT and TM238LFAC24DR : click the Communication → Serial Line 1 or Serial Line 2 entry on the left hand side. 3 Click the Protocol Settings entry. Result: The Modbus_Manager configuration window will be displayed. Set the parameters as described in the following table: Element Description Transmission Mode Specify the transmission mode to use: RTU: uses binary coding and CRC error-checking (8 data bits). ASCII: messages are in a ASCII format, LRC error-checking (7 data bits). This parameter must be identical for each Modbus device on the link. Addressing Specify if the M238 device is master or slave. Address Modbus address of the device. Time between Time to avoid bus-collision. frames (ms) This parameter must be identical for each Modbus device on the link. Serial Line Settings Parameters specified in the Serial Line configuration window. 144 EIO0000000384 04/2012
Modbus Master Modbus Slave Serial Line Configuration When the controller is configured as a Modbus Master, the following Function Blocks are supported from the PLCCommunication Library: ADDM READ_VAR SEND_RECV_MSG SINGLE_WRITE WRITE_READ_VAR WRITE_VAR For further information, see Function Block Descriptions (see SoMachine, Modbus and ASCII Read/Write Functions, PLCCommunication Library Guide) of the PLCCommunication Library (see SoMachine, Modbus and ASCII Read/Write Functions, PLCCommunication Library Guide). When the controller is configured as Modbus Slave, the following Modbus requests are supported: Types Function Function Codes Code/Sub Code Data Access (1 Bit) Physical Discrete Inputs and Outputs Read Coils 01 Read Discrete Inputs 02 Write Multiple Coils 15 Data Access Physical Input Read Holding Registers 03 (16 Bits) Registers Write Single Register 06 Write Multiple Registers 16 Read/Write Multiple Registers 23 Diagnostics Diagnostics 08 Read Device Identification 43/14 NOTE: Only located variables of the controller application can be accessed via Modbus.
