2.3.2TOSLINE-S20LP (loop) support

In addition to the standard bus connection type TOSLINE-S20 (here called S20), the optical loop connection type TOSLINE-S20LP (here called S20LP) can be used with the T3H. (SN325: T3H station module of S20LP)

By using the S20LP, high speed control-data linkage is available as same as the S20. Furthermore, peer-to-peer communication between T3H’s becomes available via S20LP.

•Up to two S20LP can be installed on a T3H. (S20LP and S20 total)

•The S20LP has 4 k words of scan transmission capacity.

The leading 2 k words of the scan memory can be assigned to T3H’s link register

(W). And the following 2 k words can be read/written by using XFER instruction.

•The S20LP does not have the scan healthy map. Therefore, SW128 to SW255 are not used for the S20LP.

•The S20LP has the loop map which indicates loop connection status of each station. This loop map can be read by using READ instruction.

•By using SEND and RECV instructions, any register data of a T3H can be sent to other T3H, and any register data of other T3H can be read into a T3H, via S20LP. (peer-to-peer communication)

NOTE

(1)The S20LP is under development.

(2)For details of the S20LP, refer to the separate manual for S20LP.
