Part III FP Instructions
F161_MRD_STATUS
Getting the statuses in RUN mode from MCU's COM port
The DUT MCU_STATUS_DUT is predefined in the FP Library.
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.
Configuration of monitor data
1. CommunicationMode (0 to 7)
(0=MEWTOCOL-COM Slave, 1=Program controlled serial communication, 2=PLC Link, 7=modem
initialization)
2. CommunicationCassette
(0=no communication cassette, 232=RS232C, 422=RS422, 485=RS485)
3. ReceptionErrorCode
(Bit 0=receive buffer overrun (hardware), bit 1=stop bit not detected, bit 2=parity unmatched)
(Bit 8=receive buffer overflow, bit 9=receive buffer full)
4. NumberReceptionErrors (number of times the reception error stored in the lower byte of
ReceptionErrorCode is detected)
5. SettingErrorCode
(Bit0=error in the DIP switch setting of the operation mode, bit1=operation mode setting exceeds the
usable limit of the unit)
(Bit 8=error in the communication parameter setting, bit 9=error in the number of transmitted data)
6. ErrorParameterNumber (0 to 11)
7. ModemInitializationStatus
Description
Status data is read from the specified COM port of a Multi-Communication Unit.
