AD-MV 55 GX

Description

The digital temperature measuring converter of series AD-MV55 GX are freely programmable digital measuring transducer with RS485 interface. Device addresses from 1 to 99 can be set via the laterally accessible address switches. The input of all characteristics directly on the device, or use the configuration software "AD-Studio". The device fulfils all tasks of a universal measuring value recording through integral function modules such as selectable relay functions, simulation modus, free linearizing curves and a wide range of supply voltage. The operating voltage is indicated by a green LED. The data communication is signaled by a yellow LED. Invalid measurement signals outside the defined measuring range are detected. In this case, the green LED flashes. The power supply as well as the RS485 bus interface is possible via the rear DIN rail connector.

Modbus Communication

The AD-MV 55 GX has an RS485 bus interface on which the Modbus RTU protocol is used. About this bus interface all measured data of the device can be read. The preset standard data format is 19200,e,8,1. Adaptation to a different data format is possible at any time. The bus address (1...99) is set to the side-mounted rotary switches. The address 0 is not permitted for the bus operation. However, on this zero position the device only via the standard data format (19200, e, 8.1) accessible. The position 0 thus represents a service position, the example can be used during parameterization error.

The AD-MV 55 GX supports two Modbus functions. These are the functions "Read Holding Registers" (0x03) and "Write Holding Registers" (0x10). With the "Read Holding Registers" function data can be read from the device and written with "Write Holding Registers" data. The individual register width is 16 bits. Please see the Modbus specification for detailed explanations of the Modbus communication. This is online available for free, but can also be purchased from the Adamczewski homepage.

The following Modbus data are accessible via the RS485 bus:
