Data transfer via communication ports

F161_MRD_STATUS

Status data is read from the specified COM port of a Multi-Communication Unit.

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
