Operands

Operand	Description
PID	The first operand. Entries are WORD data registers or constants. This is the Program ID for the communication configuration program.
F_Name	The second operand. Entries are WORD data registers or constants. This is the index and frame to send data to.
Result	The third operand. Entries are only WORD data registers. This is where the result of the transmission is stored.

Assignment Example

The following example shows how to assign values to F_Name.

F_Name

Index	Frame Number
Bits 8 ~ 15	Bits 0 ~ 7

Indexing 1

• The index number is the corresponding IP address in the communication program.
  • H00
  • H01
  • H02
  • H03

Indexing 2

• The fame number is the corresponding number in the data block section of the communication program.
  • H##00
  • H##01
  • H##02

Result Format Execution

Bit Number	Description
Bit 0	Transmission Completed: ON (1 Scan) Transmission Failed: ON (Always)
Bit 1	Transmission Failed: ON (Always)
Bit 2 ~ 7	OFF (Not Used)
Bit 8 ~ 15	Error Code (0 = No error)

Notice

Error Flag (F11.0) Notice

The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.

F11.0 turns ON if the value of the data register assigned to Size exceeds its range.

Instruction Behavior

The SEND and SENDP instructions behave as follows:

• It is required that the SEND instruction be used with a pulse contact as an execution condition, or use the SENDP instruction to prevent data transmission error.
• It is required to have an existing communication configuration program in the project.
  • If not, the instructions will not execute.
