Chapter 6: Data Communication

This section is applicable only for PM1200 power meter.

RS 485 Data Port

Data Port advantages:

 Rapid, on-line, real time readings into

 Your own SCADA software or PLC.

 Schneider Electric energy management software products such as ION™

Enterprise, Vijeo Citect, PowerLogic SCADA for pinpointing energy usage

and waste.

 Schneider Electric ConPAD: Power meter programming and basic data

reading utility.

 Data port has built-in impedance matched design for low reflectance on

long data cables at high Baud rates. Eliminates need for complicated

impedance matching resistors at the ends of long data cables.

 Fast 16 ms power meter response, average time to read 10 parameters is

90 to 100 ms (9600 Baud, Even parity, One stop bit).

 Direct reading, pre-scaled Float readings. Accurate, full precision low, and

high readings. No need for additional scaling factors or decimal

adjustment.

 Fast, easy-to-use grouping of parameters tuned for field requirements.

 TURBO area for single point polling (upto 50 per query)

 Block area for even faster access to pre-configured data blocks
