Automation Products Group Modbus® Register Tables Serial Communication

WARNING

As is typical with most instruments, the addition of serial communications carries an inherent risk; it allows a remote operator to change the operation and/or characteristics of the device being digitally communicated with (in this case, the meter). Inappropriate communication could have serious consequences in meter or system operation.

Ultimately, it is up to the system designer to provide for the safe operation of a process. But certainly, no single event should make the difference between a safe situation and a catastrophe. Please use the appropriate level of caution when implementing serial communication.

CAUTION: If the Interlock Relay function is being used on the meter, its proper operation can be affected by inappropriate digital

communications. Please take the steps necessary to provide for reliable interlock protection.

Automation Products Group Modbus® Register Tables Serial Communication

Introduction

This document describes how to communicate with the DDD, DBD, DDL, and DDX series of meters, with firmware version 3.200 & greater, using the Modbus® RTU Serial Communication Protocol. The user should be familiar with Modbus serial communication and the meters. Refer to the meter instruction manual and the serial communication adapters’ manual for setup and wiring instructions.

Go to http://www.modbus.org/ to obtain a copy of the Modbus Specifications and to find Modbus Technical Resources.

Note that although there are no specific 3x Registers, all 4x Registers are mirrored into 3x register space, and are therefore capable of being read by Modbus function 04

(Read Input Registers).

Comments

Actually represents -50.0 to +50.0. Offset value is only applied to temperature inputs. If Adjust is greater than 27.7°C and the temperature units are switched to °F, it will be set to 50.0

(lower than -27.7, set to -50.0).

Value represents the number of parallel RTDs connected to the signal input. Any other value than these results in a setting of 1.

Actually represents 0.1 to 99.9 setting.

Actually represents 2.0 to 999.9 setting.

Display filtering. 0 = no filtering. 2 to 199 = old + ((new - old)/Filter). For pulse input 900 = Hi-Speed, 202 to 250 = Lo-Speed where the range is 2 to 50.

Actually represents 0.2 to 99.9. If the input steps greater than the bypass value, it will be displayed immediately, with no filtering occurring. The number represents percent of full-scale for process inputs and °F for temperature inputs. No effect if filter = 0.

Changes to this register are saved but don’t take effect until next meter reset (Modbus command or power-up). Writing out of range data results in an address of 247.

0 = 300, 1 = 600, 2 = 1200, 3 = 2400, 4 = 4800, 5 = 9600, & 6 = 19200. Changes to this register are saved but don’t take effect until next meter reset (Modbus command or power-up). Writing out of range data results in a baud rate of 2400.

Transmit delay to minimize collisions on the RS-485 network.

0 = None with 1 stop bit, 1 = None with 2 stop bits, 2 = Odd, 3 = Even. Changes to this register are saved but don’t take effect until next meter re-initialization (Writing 0xFF00 to 40299 or power-up). Writing out of range data results in a parity setting of Even.

This is the timeout between bytes of a Modbus frame. Note that a value less than the minimum value for the present baud rate cannot be saved. Minimums are: 300 baud = 0.06 sec, 600 = 0.03, 1200 = 0.02 and 0.01 for 2400 to 19200. Changes to this register are saved but don’t take effect until next meter reset (Modbus command or power-up). Writing out of range data results in a timeout of

2.54 seconds.

0 = Linear, 1 = Square Root, 2 = Exponent, 3 = Round Horizontal Tank

This register is only used when register 40137 = 0 Linear.

Ch-A voltage input number of points uses register 40188.

Display Rounding

Acceptable Index values are:

0=1, 1=2, 2=5, 3=10, 4=20, 5=50, and 6=100

This sets the meter units as follows:

0 = LB, 1= kG, 2 = Ounce, 3 = grams, 4 = Ton, 5 = Metric Ton,

6 = Custom. Custom is specified in reg 40119 thru 40124

Represents the Gross display value including the decimal point. Under Range = -99999, Over Range = 999999

Represents the Net display value including the decimal point. Under Range = -99999, Over Range = 999999

Represents the Net display value including the decimal point. Under Range = -210.00, Over Range = 210.00

Represents the Custom Units Little Display MSD (Most Significant Digit)

value. The hex value represents the allowable ASCII character.

Represents the Custom Units Little Display MSD-1 value. The hex value

represents the allowable ASCII character.

Represents the Custom Units Little Display MSD-2 value. The hex value

represents the allowable ASCII character.

Represents the Custom Units Little Display MSD-3 value. The hex value

represents the allowable ASCII character.

Represents the Custom Units Little Display MSD-4 value. The hex value

represents the allowable ASCII character.

Represents the Custom Units Little Display MSD-5 value. The hex value

represents the allowable ASCII character.
