SEL Communications Processor Example
➤ ,03:USER: is an SEL communications processor Unsolicited
Write message compatibility requirement. 03 is the SEL
communications processor port the SEL-2414 is connected and
the second parameter should always be USER, or F800h.
➤ 0000H/ indicates the first SEL-2414 Remote Analog to begin
writing to (0000H = RA01 – 003EH = RA32)
➤ The \ and / frames the message.
See the SEL communications processor manual for more information regarding
the Unsolicited Write message string.
Below are 16-bit register data that are stored in the User region of port 6 which
we will send to the SEL-2414 on Port 3. Remember that F800H is synonymous
with the start of the USER region in the SEL communications processor. One
register stores one Integer and 2 registers store one Float or Long data type.

Starting at register 0000h, the first 4 registers contain 4 Integer data values
7FFFh 8001h FFFFh 0000h
Starting at register 0004h the next 8 registers contain 4 Float data values
447Ah 25C3h C47Ah 270Ah 4516h B029h 4516h AFD7h
Starting at register 000Ch the next 8 registers contain 4 Long data Values.

Setting the SEL-2414
The SEL-2414 interprets Remote Analogs as Integer, Float, or Long data types.
For correct remote analog data transfer, the data type sent from the SEL commu-
nications processor must match the data type of each of the SEL-2414 Remote
Analogs. Use the RAnnTYPE settings (Report settings) to declare the Remote
Analog type (I = Integer, F = Float, L = Long). Assume in our example we need
only RA01 through RA12. In this example, we send 4 Integers, 4 Floats, and
4 Longs to the SEL-2414. Figure C.6 shows the correct settings for RA01
through RA13 accordingly, starting at RA01.
