  • Page 18: Modbus Rtu Serial Communication Port

    The Modbus RTU implementation is designed to provide a popular data exchange format connecting the UDA to both Honeywell and foreign master devices via the optional serial communication port. Modbus RTU allows the instrument to be a citizen on a data link shared with other devices, which subscribe to the Modicon Modbus Protocol Reference Guide PI-MBUS-300 Rev.

  • Page 19: Modbus Rtu Link Layer

    Errors detected by the data layer are rejected and the slave responds to the polling device with a Modbus- type status exception error. A summary of the Modbus status exception codes is listed in Section 9 - Modbus RTU Exception Codes. January 09 UDA2182 Communications User Guide...

    5. Modbus/TCP Interface 5.1 Introduction UDA2182 supports the Modbus/TCP (also called Modbus TCP/IP or Modbus Ethernet) protocol for communications with third party HMI and SCADA software via a direct Ethernet TCP/IP connection. The UDA’s optional Ethernet 10/100Base-T Host port is used for the Modbus/TCP connection. Ethernet TCP allows multiple concurrent connections to hosts for data interchange.

  • Page 28 Modbus Double Register Format The default Big Endian format (Word Swap = Yes) is used with SpecView32 or Honeywell’s PlantScape/Experion/EBI software and follows the “Honeywell” default format of other control and recording products. It should be noted that most PC software packages offer a register (word) swap selection in their driver package anyway, so there should never be an incompatibility.
