[S20 message transmission (Computer link binary)]
The L1 function of S20 message transmission is described below.
The T3H/S2T can access the CPU module L1PU12H for its data through the TOSLINE-
S20LP.
The T3H, for example, sends a write/read request to the L1 using a SEND/RECV
instruction. It is not necessary for the L1 to have an application.
The L1 accepts only messages of computer link binary mode. (When the T3H, for
example, 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).)
Example of binary connection through TOSLINE-S20LP
In this example, T3H is station 1; L1,
station 2. (The T3H sends test data to
the L1 through the S20LP, and receives a
response from it.)
Note: Use the L1PU12H (double board capable of accessing the DPRAM of the TL-
S20LP) in connecting the TOSLINE-S20LP. (See the table below.)
