Page 6: Section 1 - Introduction
SECTION 1 - INTRODUCTION General The RTK 725B Series alarm annunciator is used to inform the operator that a process has gone beyond set limits using visual and audible alarms. The Annunciator is manufactured from universal cells which can be assembled in an array to provide the number of rows and columns required to suit individual panel designs.
Page 7: Glossary Of Terms
INM725B 725B Instruction Manual – Rev 21 Glossary of Terms Cell: A single module 60mm x 60mm which can be joined to adjacent cells in varying heights and widths to provide the number of alarms required. The number of alarms available per Cell depends on the window size required.

RTK AMS When used with the optional Indicium RTK Alarm Management System the user needs to set the protocol to RTK AMS Slave Protocol in the drop down menu for communication to be established between the 725B and the associated PC based Indicium software.
Page 112: Mapping
INM725B 725B Instruction Manual – Rev 21 Mapping Mapping is configured using the mapping spreadsheet. The spreadsheet is used to map port data to channels and also to setup the Modbus master block requests. Global Settings The Global settings worksheet shows the global setting configured on the unit when the mapping has been exported.
Page 113 INM725B 725B Instruction Manual – Rev 21 Setting up master data blocks (Master protocol only) In columns A and B (Source) the slave device node address and register addresses can be entered. This can be one continuous block or if more than one slave device is used up to 16 devices can be set up.
Page 114 INM725B 725B Instruction Manual – Rev 21 The example below shows 3 separate blocks with one block with gaps. First block has node address 1, start register 40001 and 8 registers Block has node address 2, start register 40001 and 8 registers block has node address 3, start address 40001 and 15 registers with registers 40005, 40006 and 400013 unused.
Page 115 INM725B 725B Instruction Manual – Rev 21 One to one Mapping If one to one mapping is required the spreadsheet is still required to set-up the master node address, Start address and number of registers. The output can then be entered in channel order to configure the one to one mapping. Alternatively if the user sets mapped port to None in the mapping tab the unit will default to one to one on all ports.
Page 116 INM725B 725B Instruction Manual – Rev 21 Many to one Mapping Many registers/coils can be mapped to the same channel on the annunciator. They will be OR’d together so the channel will show the OR’d sum of all the mapped sources. The Reflash sequence on the channel can be used to reflash the alarm window if any of the source data changes state.
Page 117 INM725B 725B Instruction Manual – Rev 21 Slave Mapping The slave spreadsheet allow the Port register to be mapped to the required channel. This work in the same way as the Master but columns A and B show the P725B port register addresses. Mapping Limits On the P725B the number of mapped points is limited to 656, this only includes mapped points, one to one points are not included in the mapping...
