4. When applying GPS instruction, COM1 has to be applied in Master mode, i.e. M1312 has to
be enabled to sending request. In addition, M1314 = ON indicates receiving completed.
M1315 = ON indicates receiving error. (D1250 = K1, receiving time-out; D1250 = K2,
checksum error)
5. Associated M flags and special D registers:
No. Function
M1312 COM1 (RS-232) sending request
M1313 COM1 (RS-232) ready for data receiving
M1314 COM1 (RS-232) data receiving completed
M1315 COM1 (RS-232) data receiving error
M1138 Retaining communication setting of COM1
D1036 COM1 (RS-232) Communication protocol
D1249 COM1 (RS-232) data receiving time-out setting. (Suggested value: >1s)
D1250 COM1 (RS-232) communication error code
6. Before applying the received GPS data, please check the value in D+9. If D+9 = 0, the GPS
data is invalid.
7. If data receiving error occurs, the previous data in D registers will not be cleared, i.e. the
previous received data remains intact.
