MULTI GAUGE CONTROLLER OPERATION • Degassing voltage - May be set between 400 and 600V. The MG15 is used during degassing the electron bombardment method. It is recommended to carry out degassing at the highest voltage admissible by the gauge. At a higher voltage a lower emission current is required to obtain the same degassing power, which affects positively the life of the ilament.

Page 81: Communication
This chapter is intended for users who want to use Modbus RTU, Modbus TCP (Ethernet) or Pro iNet communication links. These are communication protocols used to control the functioning of the MG15 . The following chapter includes general information about standards, wiring and electrical connec- tions.
Page 82: Precautions
COMMUNICATION MULTI GAUGE CONTROLLER 6.1.1.1 GENERAL WIRING RULES 1. Communication cables should be laid separately and as far as possible from the power supply cables or cables supplying power to external equipment such as contactors, relays or motors. 2. Communication cables may be laid together with signal cables if those cables are not exposed to sources of interference.
Page 83: Grounding
The device in the remote control mode displays in the upper part of the window an information bar with text: ”MG15 - REMOTE”. The remote control mode can be activated in the device only via software.
Page 84: Communication Interfaces
Descriptions of the connections for individual protocols are presented below. The RS232/RS485, ETH and Pro inet ports of the MG15 are not optically iso- lated. Therefore, it is necessary to ensure the same potentials between the con- troller(s) and other devices in this bus (common power supply chassis ground).

Page 87: Modbus Protocol
During communication with the device through the Ethernet (Modbus TCP) network its IP address is the unique address. The data register map is unique for the MG15 device and its de inition is given in the tables starting from ??.
Page 88: Interface Configuration
6.5. Transmission is executed as encapsulation of the Modbus RTU protocol frame in the Pro iNet frame. This means that the MG15 is visible in the network as a standard device compatible with the Pro iNet standard and an IP address is assigned to it. Communication, however is executed by formulating appropriate queries compatible with the Modbus RTU protocol and sending them in a frame of the Pro iNet protocol to the Slave device.
Page 89: Modbus Rtu
“common” signal should be used to ensure addi- tional protection against interference. Note 3: The MG15 works in a half-duplex system, which does not enable transmission and reception of data in the same time. Data are transmitted interchangeably, once query, once response.

The next problem are variables, for which 16-bit representation is not suf icient, e.g. value of vac- uum. To solve these problem, different types of variables have been implemented in the MG15, enabling the full resolution of data. The most precise data type is 32-bit loat in the ”IEEE-754” standard. This format is written in the memory as two consecutive words (4 bytes) in the order: “MSB irst”.
