TOSLINE-S20LP message transmission
[S20 message transmission (Computer link binary)]
The LC51* function of S20 message transmission is described below.
The T3H/S2T can access the LC51* for its data through the TOSLINE-S20LP.
The T3H, for example, sends a write/read request to the LC51* using a SEND/RECV
instruction. It is not necessary for the LC51* to have an application.
The LC51* accepts only messages of computer link binary mode. (When the T3H, forexample,
uses a SEND/RECV instruction, it must make a request in binary mode.
Specifically, 8000H must be set for the transfer parameter request code (normally 0.).
In this example, T3H is station 1; LC51*, station 2.
(The T3H sends test data to the LC51* through the
S20LP, and receives a response from it.)
