1 General
1.1 Introduction
This implementation of the MODBUS® communication protocol (ASCII and
RTU mode) in the TAPCON® 230 AVT is based on the Modicon MODBUS1 Pro-
tocol Reference Guide, PI-MBUS-300 Rev. J, copyright 1996 by Modicon Inc.
This document details the implementation subset available in a TAPCON® 230
AVT voltage controller equipped with the optional communication interface
module (CI-module).
Refer to the documentation of TAPCON® 230 AVT available at Maschinenfabrik
Reinhausen or www.reinhausen.com for additional information on the
TAPCON® 230 AVT voltage controller.

2 Communication Interface Ports
For data transfer via MODBUS protocol the voltage regulator provides the foll-
wing communication interface ports:
Ethernet Optical Fiber RS 485 RS 232
Figure 1 Communication Interface Ports
RS-232
9 pin female SUB-D connector
Pin 2: TxD
Pin 3: RxD
Pin 5: GND
RS-485
3 pin male connector from Phönix MSTB 2,5/3-GF-5
Pin 1: GND (100 Ohm ground resistance)
Pin 2: B (inverting)
Pin 3: A (non inverting)
Polarity:
A > B for more than 200 mV equates to 1
B < A for more than 200 mV equates to 0
A disabled communication line equates to 1
The Startbit is labled with 0
The recommended terminating resistor is 120 Ohm.

Pin 2: Tx-
Pin 3: Rx+
Pin 6: Rx-

2.1 Settings on the voltage regulator
Getting started with MODBUS communication some parameters must be set on
the TAPCON® 230 AVT.
MENU-key > Configuration > Continue > Continue > Comm. Interface

IP address Not used
TCP port Not used
Light On/Off Mode Not used
Local SCADA address 1..255 (0 = broadcast)
SCADA master address Not used for MODBUS
Unsolicited messages Not used for MODBUS
Unsolicited retries Not used for MODBUS
Application confirm timeout Not used for MODBUS
RS-485 transmit delay time 0..254 ms*
*) E.g. 2 ms to compensate the reaction time needed by the RS-485/RS-232
converter to switch from send mode to receive mode.
2.1.3 Ethernet (RJ45)
Communication protocol MODBUS RTU over tCP
Communication port RJ45
Communication baud rate fixed 19200 Baud
IP address 0.0.0.0
TCP port 1234

Local SCADA address 1..255 (0 = broadcast)
SCADA master address Not used for MODBUS
Unsolicited messages Not used for MODBUS
Unsolicited retries Not used for MODBUS
Application confirm timeout Not used for MODBUS
RS-485 transmit delay time Not used
Note: This is not MODBUS TCP!
Simply put, this is a Modbus RTU message transmitted with a TCP/IP wrapper
and sent over a network instead of serial lines.

3.3 MODBUS adressing model
General notes:
Multiple communication links are not supported.
Communication is half-duplex mode.
Addresses in this document refers to the MODBUS PDU addresses.
Example: Reading input status with address 8 will read address 7 in the Discrete
Input block of the MODBUS data model.
