PROBLEM TO BE SOLVED: To store a communication data between a main device and a communication opposite party in a channel monitoring device, in response to communication opposite party. SOLUTION: A switching instruction signal generator 32 generates switch instruction signals K1 and K2, which select one of serial communication data between a master device 10 and slave devices, and switch it to serial transmission reception data R0, and transmits the signals K1 and K2 to the master device 10. A switching instruction signal storage section 33 stores the switching instruction signals K1 and K2 transmitted from the switching instruction signal generator 32. A serial/parallel conversion section 31 converts the serial transmission reception data R0, which is switched selectively by the switch instruction signals K1 and K2 and transmitted from the master device 10, into parallel data. CPU 35 stores the parallel data in the data storage areas 341-343 designated by the signals K1 and K2 which are read out of the switching instruction signal storage section 33. |
