FHSD8310 Modbus Protocol Guide for ModuLaser Aspirating System
Product Information
The Modbus Protocol Guide for ModuLaser Aspirating Systems is a technical reference manual that describes the Modbus holding registers used with ModuLaser command display modules to monitor ModuLaser aspirating smoke detection systems. The guide is intended for experienced engineers and contains technical terms that may require an in-depth understanding of the issues involved. The ModuLaser name and logo are trademarks of Carrier, and other trade names used in this document may be trademarks or registered trademarks of the manufacturers or vendors of the respective products. Carrier Fire & Security B.V., Kelvinstraat 7, NL-6003 DH, Weert, The Netherlands, is the authorized EU manufacturing representative. Installation in accordance with this manual, applicable codes, and the instructions of the authority having jurisdiction is mandatory.
Product Usage Instructions
Before creating Modbus applications, read this guide, all related product documentation, and all related Modbus protocol standards and specifications entirely. The advisory messages used in this document are shown and described below:
- WARNING: Warning messages advise you of hazards that could result in injury or loss of life. They tell you which actions to take or to avoid to prevent injury or loss of life.
- Caution: Caution messages advise you of possible equipment damage. They tell you which actions to take or to avoid to prevent damage.
- Note: Note messages advise you of the possible loss of time or effort. They describe how to avoid the loss. Notes are also used to point out important information that you should read.
The Modbus connections are maintained via Modbus TCP using a ModuLaser command display module. Figure 1 shows the connection overview. The command display module configuration is also described in the manual. The guide includes a global register map, ModuLaser network status, device status, Modulaser network faults and warnings, device faults and warnings, detector output level, network revision number, execute reset, and execute device enable/disable.

Modbus connections
Connections
Communications are maintained via Modbus TCP using a ModuLaser command display module.
Figure 1: Connection overview 
Command display module configuration
Modbus is available for ModuLaser command display modules with firmware version 1.4 or later.
To ensure full compatibility, we recommend that all modules in a network are updated to firmware version 1.4 if any module in the network has firmware version 1.4 (or later).
By default Modbus functionality is disabled. Enable Modbus from the command display module TFT display menu or by using the Remote configuration application (version 5.2 or later).
Modbus connections may be configured from a single point by specifying the destination IP address. Indicating 0.0.0.0 allows Modbus connection to the network from any accessible point
Timing considerations
Reading and writing holding registers is a synchronous operation.
The table below gives the minimum times that must be maintained between consecutive operations. For optimum reliability, third-party software should conform to these specifications.
Caution: Do not send multiple operations without first receiving a response from the device.
| Function | Minimum time between operations |
| Read Holding Register | As soon as device responds. |
| Bus Reset | 2 seconds |
| Isolate | 3 seconds |
