Andel Bundguard 5 - Registers; Discrete Inputs

Bundguard 5 12.01.2022 Rev.4
16
This table shows the data structure for floating point MODBUS register values.
4.1.10.1 Registers
The BundGuard issue 5 supports the MODBUS RTU protocol via RS232 or RS485. The serial protocol is
configured in the menu system. The BundGuard issue 5 supports the full MODBUS RTU specification,
including extended individual and stream access to device identification objects. Full details of these
functions are detailed in the MODBUS application specification.
Any values that span more than one register address, are always little-endian format.
Available data via the MODBUS interface is provided in the registers detailed below:
4.1.10.2 Discrete inputs
Discrete inputs are read-only Boolean bits that indicate the ON/OFF state of a certain feature or alarm.
These can be accessed through use of correctly formatted MODBUS protocol read-coil functions
detailed in the MODBUS specification.
