AD-MV 550 GVD

Description

The digital temperature measuring transformer AD-MV 550 GVD serves the galvanic separation and transformation of resistance transmitter or thermocouples to an impressed output signal (i.e. 0-20 mA). All measuring ranges and outputs can be freely parameterized. This can be carried out via the optional control panel AD-VarioControl or via the programming software AD-Studio. Due to its current-sinking output, transmitter signals can also be galvanic separated or transformed. The wide range power pack covers all supply regions.

Modbus Communication

The optional AD-VarioConnect operating module has an RS-485 interface. The data is transferred via the Modbus RTU protocol, the AD-VarioConnect operating module represents a Modbus slave. Communication takes place according to the master-slave procedure and starts with a request from the master, e.g. from a PLC or a PC. Each bus participant must have a unique address. If a slave detects that its address has been addressed by the master, the slave always sends an answer. The slaves never communicate with each other. They are also not able to start a communication with the master.
The Modbus master can read out the individual registers of the AD-MB 550 GVD via the addresses.
The default standard data format is 19200,e,8,1 with slave address 1. These settings can be changed via the AD-VarioConnect operating module.
