2.4.6 Network data receive (RECV)
FUN 240 RECV Network data receive
Expression
Input ─[ A RECV B ]─ Output
Function
This instruction reads the designated range of register data from another T3H through the network.
(Network: TOSLINE-S20LP or Ethernet)
The transfer source register (target-station) is designated by A+5 and A+6.
The transfer destination register (self-station) is designated by A+3 and A+4.
The transfer size (number of words) is designated by A+2. The maximum transfer size is 128 words (S20LP),
or 485 words (Ethernet).
The designation method of the target-station is different between S20LP and Ethernet.
This instruction is also used for other functions of the Ethernet module. Refer to the Ethernet module (EN311)
manual for detailed functions used for the EN311.
