81SCU200 INSITE ENERGY MANAGEMENT SYSTEM
• Polarity of sensors (for DC currents)
These registers contain the configured nominal current value and the DC polarity information of each
sensor with following bit format:
000P RRRR RRRR RRRR
• R Reserved for future use
• P DC polarity information
• 0 = direct, DC current coming out of the cone is displayed positive
• 1 = reverse, DC current coming out of the cone is displayed negative This setting has influence on all
DC values of the specified sensor
• 0000h DC polarity direct
• 1000h DC polarity reverse
This data has to be set user while system configuration. Factory default value is 0000h.
Serial number (SID), version and bus line of sensors
These registers contain system information about each sensor.
This data has to be set user while system configuration. Factory default value is 0000h.
• Serial number (SID), version and bus line of sensors
These registers contain system information about each sensor
Offset Words Data
0h 4 Unique Serial Number (SID)
4h 2 HW version
6h 3 SW version
9h 1 Measurement Range (0.1A steps)
Ah 1 Enabled Data Types (as in InSite Bus Protocol defined)
Bh 4 Reserved
Fh 1 ID of internal bus line sensor is connected to 0: no sensor, 1: line 1, 2: line 2
• Each sensor has a unique serial number needed for setup procedure on internal InSite bus.
• HW and SW version of sensor are readable for diagnosis purpose.
• “ID of internal bus line” identifies the Control Unit’s internal bus line the sensor is connected to.
This data is not hold always in registers but will be prepared on read request.
