Central interface modules Siemens

Обзор

The central interface module is the intelligent processor module of the SIPLUS HCS724I heater control.

Дизайн

• Module encapsulated in metal enclosure
• Two LEDs for normal operation (green) and fault (red)
• PROFIBUS DP interface (up to 12 Mbaud)
• Rotary switch for setting the PROFIBUS DP address
• RS 232 C serial port
• Parallel bus interface to the power output modules
• Connection facility for up to 16 LA724I/LA724I HP/LA724I SSR power output modules per central interface module
• Expansion slot for line-voltage sensing submodule (option)

Функции

Communications

PROFIBUS DP

• Import of the parameter settings from the higher-level controller
• Transfer of the diagnostic information to the higher-level controller

Parallel bus (internal)

• Control and monitoring of max. 384 power output channels

Performance features

• Calculation of heat emitter control variables of power output channels
• Setpoints adjustable from 0% to 100% in steps of 0.5%
• Uniform load distribution over all power output channels and over all the SIPLUS HCS724I heating controllers operated in the group
• Simple adaptation to the respective production process by selecting one of up to four operating modes
• Mixed operation of the various power output modules is possible

Diagnostics

• Evaluation of diagnostics information from connected power output modules
• Phase-sequence detection indicating whether phases L1, L2, and L3 are correctly connected
• Automatic detection of the line frequency

Line synchronization

In order to ensure synchronization of the power output modules with the connected power supply, the system is synchronized with phase L1. The respective switch-on times for phases L2 and L3 are then calculated automatically.
