Reading Data Received at Port 1
00FE: Master's node address 00, Master's unit ad-
dress FE Hex
DM 0200: Command data storage words
0009 Hex: Master's unit number 00, 9 command data
words (BCD)
If the Equals Flag is OFF (error in writing to the Mas-
ter), IR 03200 will be turned ON, and the data will be
transmitted again.
If the Equals Flag is ON (writing to the Master has
been completed normally), IR 03200 will be cleared
(message transmission completed).
When IR 03200 turns ON, the CPU Unit will
check that IR 10112 (unit no. 0 Master's Mes-
sage Communications Enabled Flag) is ON,
and message transmission will start.
If SR 35802 (Port 1 RS-232C Receiving Flag) is OFF
and SR 35803 (Port 1 RS-232C Received Flag) is
ON, the sequential processing control bit IR 03200
will be turned ON.
