Central processing unit

The central processing unit JUMO variTRON 300 along with the proven input and output modules (incl.
controller module) as well as the router modules (primarily router module 1-port, 705043) form a com-
plete system.
The central processing unit manages all configuration and parameter data of the complete system and
makes a PLC acc. to IEC 61131-3 (CODESYS V3.5) available (extra code). The PLC can be activated
in different versions:
• CODESYS runtime system
• CODESYS runtime system incl. Remote TargetVisu
• CODESYS runtime system incl. WebVisu
• CODESYS runtime system incl. Remote TargetVisu and WebVisu
For visualization, commercially available panels are used which support CODESYS Remote TargetVisu
or WebVisu functionality. The visualization is also possible via web browser. Visualizations have to be
implemented with CODESYS resources (see order details).
A convenient setup program is used for configuration. JUMO standard functions for CODESYS are pro-
vided in libraries (as of system version 6) and can be individually integrated into the customer applica-
tion.
As of system version 5, the central processing unit JUMO variTRON 300 is also optionally usable as a
receiver for the JUMO Wtrans transmitters, thereby enabling wireless transmission of measured values.
