Connecting Interfaces; Position Of The Interfaces - JUMO mTRON T Manual

2.1

Position of the interfaces

The central processing unit is equipped with a standard LAN interface. It is designed to transmit
data using the HTTP protocol (e.g. PC with setup program or Web browser) or the Modbus pro-
tocol (Modbus/TCP, master or slave).
Two serial interfaces are also optionally available as additional modules for the central process-
ing unit (Com1 and Com2, 9-pin), which can be used as a RS232 or RS422/485. Both serial
interfaces can be operated using the Modbus protocol (Modbus RTU; master or slave).
NOTE!
The type designation on the central processing unit's nameplate provides information on
which optional interfaces were assembled ex-works.
Information on this can be found in the chapter "Identifying the device version" in the operat-
ing manual B 705001.0 or the installation instructions B 705001.4 (the installation instruc-
tions are included in the scope of delivery of the central processing unit).
NOTE!
Optional interfaces can also be added by the user.
Information on this can be found in the chapter "Retrofitting interfaces" in the operating man-
ual B 705001.0 or the installation instructions B 705001.4 (the installation instructions are in-
cluded in the scope of delivery of the central processing unit).
