Advanced I/O Instructions

5-31-1 7-SEGMENT DISPLAY OUTPUT – 7SEG(88)

The port specifier was not 1 or 2.

PMCR(––) executes communications sequence 101 when IR 00000 is ON

and SR 20708 (the Port 1 Protocol Macro Executing Flag) is OFF. DM 0100

contains 0003, so the next two words (DM 0101 and DM 0102) are used as

the send data.

Received data is stored in the range of words beginning at DM 0201 and the

number of words received is automatically written to DM 0200 (the first

receive word.)

Note The symbol read option, R( ), in the send message, or the symbol write

option, W( ), actually sends/receives data.

Ladder Symbols

Do not use 7SEG(88) more than twice in the program.

When the execution condition is OFF, 7SEG(88) is not executed. When the

execution condition is ON, 7SEG(88) reads the source data (either 4 or 8-

digit), converts it to 7-segment display data, and outputs that data to the 7-

segment display connected to the output indicated by O.
