Where an SNT10D Unit Is Used
The SNT10D is used for S2SC70, SSC60, SSC50, SSC57, and SNB10D to allow the
SNT401/SNT411 and SNT501/SNT511 modules to be chain-connected to each other. In such a
case, the number of I/O modules that can be installed on each unit is six to eight. This can result
in the same installation as in ESB-bus cable connections on the ESB bus.
