Part III FP Instructions
22.4 Data transfer in program controlled mode
For all PLC types and all COM ports (including the COM ports of the Multi-Communication Unit) the following
instructions are available:
 Tool instructions:
- SendCharacters (see page 737)
- SendCharactersAndClearString (see page 739)
- ReceiveData (see page 750)
- ReceiveCharacters (see page 752)
- ClearReceiveBuffer (see page 753)
 FP instructions
- F159_MTRN (see page 741), sending (see page 733) in program controlled mode
- F161_MRCV (see page 755), receiving (see page 747) in program controlled mode
 Flag evaluation:
- IsTransmissionDone (see page 763)
- IsReceptionDone (see page 760)
- IsReceptionDoneByTimeOut (see page 761)
- IsCommunicationError (see page 764)

NOTE
F159_MTRN (see page 741) allows multiple communication ports to be accommodated. This
instruction is an updated version of F144_TRNS. Both instructions are compatible with all PLCs:
PLCs with multiple communication ports will compile F144_TRNS s, n to F159_MTRN s_Start,
n_Number, d_Port*=1. PLCs with only one communication port will compile F159_MTRN to
F144_TRNS s, n.
22.4.1 Sending data to external devices
Steps for sending data to external devices:
1. Setting the communication parameters to match the external device
2. Generating the data in the send buffer
3. Sending the data using the instruction F159_MTRN
