<2. AMPLIFIER FOR MODBUS COMMUNICATION > 2-1 2. AMPLIFIER FOR MODBUS COMMUNICATION Refer to IM 01R04B04-00E for the details of the amplifier. This section encompasses topics applicable to only the Modbus communication type. (1) The Modbus communication type has only one current output (Iout1). (2) For the Modbus communication type intrinsically safe outputs are not available. (3) Concurrent write access via Modbus and HART should be avoided.

<3. ABOUT MODBUS> 3-1 3. ABOUT MODBUS 3.1 Outline MODBUS is a bi-directional digital communication protocol also for field devices, which offers an advancement in communication speed and is widely employed by numerous field devices. The MODBUS communication type of the Rotamass employs the specification standardized by the MODBUS Organization, and provides interoperability with devices produced by other manufacturers.
3-2 <3. ABOUT MODBUS>> Figure 3.1 Device Connection Before using a MODBUS configuration tool other than the existing host, confirm it does not affect the loop functionality in which all devices are already installed in operation. Disconnect the relevant control loop from the bus if necessary. IM 01R04B08-00E-E 1st edition February 15, 2012 -00 All Rights Reserved.
<4. GETTING STARTED> 4-1 4. GETTING STARTED MODBUS is digital communication protocol and differs in operation from 4 to 20 mA transmission and the HART communication. It is recommended that users use MODBUS devices in accordance with the procedures described in this section. The procedures assume that MODBUS devices will be set up on a bench of an instrument shop. 4.1 Wiring in ROTAMASS 3 Terminal Box Figure 4.
4-2 <4. GETTING STARTED> 4.2 Communication Setting To activate MODBUS, the following settings are required. They are located in the MODBUS Communication menu in Detailed Setup. IMPORTANT Connecting the ROTAMASS MODBUS communication tool to a bus with its existing host may cause communication data scrambles resulting in a functional disorder or a system failure. IMPORTANT Do not turn off the power supply immediately after setting.
<4. GETTING STARTED> 4-3 4.3 Reading and Writing Values Unlike other communication protocols MODBUS does not use standardized device description files but store data and parameters in registers. An overview of the Modbus registers of ROTAMASS can be found in chapter 7. For configuration the ROTAMASS MODBUS communication tool is available from Yokogawa which can address parameters of ROTAMASS which are mapped onto MODBUS. The tool can be found on the DVD which is attached to each device.

TECHNICAL DETAILS OF MODBUS COMMUNICATION 8.1 Range check According to the Modbus specification error bit and exception codes are only defined for physical transmission errors. Therefore there is no possibility to signal logical errors like violation of data ranges or invalid selections at the time when a register is being written. ROTAMASS 3 Series Modbus communication type will check all values written via Modbus.
8-2 <8. TECHNICAL DETAILS OF MODBUS COMMUNICATION> 8.3 Transmission of status information Modbus protocol is designed to reduce overhead. Therefore there is no continuous transmission of status information. ROTAMASS 3 Series Modbus communication type provides three holding and input registers to read the current status of error (HR 896, IR 42), alarm (HR 912, IR 43) and warning (HR 928, IR 44) messages at the time when the registers are being read.
