Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to the controller.
In protocol option part, you can set the following: whether to check CRC(1 = check, 0 = No check), bit write value that corresponds to ON(Default = 65280), protocol type(1 = IP protocol, 0 = Serial protocol), bit write value that corresponds to OFF(Default = 0), whether to use WORD size(1 = Not using WORD size, 0 = using WORD size, Default = 0), whether to use multi write(0 = Not using multi write, 1 = using multi write, Default = 0), state value storage position for comparison of data(input WORD memory address, Defualt = 1000). Each argument is a comma-delimited.
Note) Baud rate, parity bit, data bit, stop bit can set by using front panet switch or write setting.
COM1, COM2 of ION series controller use RS-232C, RS-485 communication port.
ION series controller use DLL-MODBUS2 communication driver. So you havet to set 'MODBUS RTU' protocol at setting of power meter.

Range of word data are as follows.
. Normal input : 0 ~ 6553. modbus data expression value : 0 ~ 65530. So, you have to read value x 10 : SCADA Server ratio= (max-min) x 10.
. Voltage data (154,000 V, 22,900 V, ..) can't display normal input range. You can solve this problem as follows :
1) Change the value of 7150 address data( word area maximum value of normal input data ) to 65535, 655350 or 6553500 by using 'analog write'. ( Extra1 of analog tag : 16d )
2) Change the value of 7166 address data( word area maximum value of normal output data ) to 65535 by using 'analog write'. ( Extra1 of analog tag : 16d )
