In general, the custom pages will be written in HTML with a special delimiter
that tells the EGX400 to dynamically get register information from a device.
The delimiter at the beginning of a string is (PL__) and the delimiter at the
end is (__PL). This tells the EGX400 to parse this string and dynamically fill
it with register data. Table 1 lists the supported POWERLOGIC tags.
Function Code POWERLOGIC TAG
<DeviceID>^<StartingRegisterAddress>[<NumberOfRegisters>]
SyMax Function Code 0 example tag = PL__1^1003[5]__PL
example of data returned = 85,86,84,25,56
SyMax Function Code 4 <DeviceID>^<RegisterAddress1>,<RegisterAddress2>,etc
example tag = PL__1^1003,1004,1005,1006,1007__PL
example of data returned = 85,86,84,25,56
Modbus Function Code 1 <DeviceID>^C<StartingCoilAddress>[<NumberOfCoils>]
example tag = PL__1^C1003[5]__PL
example of data returned = 1,0,0,1,1
Modbus Function Code 2 <DeviceID>^D<StartingInputAddress>[<NumberOfInputs>]
example tag = PL__1^D1003[5]__PL
example of data returned = 1,0,0,1,1
Modbus Function Code 3 <DeviceID>^H<StartingRegisterAddress>[<NumberOfRegisters>]
