Will TSXSAY100 communicate with a TeSys LF3MP06EU ?

Issue: Compatibility

Product Line: TSX Platform,

Environment: ASi

Cause: version difference


In our Catalog, we have two Asi Primaries:

TSXSAY100    ASi V1
TSXSAY1000  ASi V2.

The TesysLF range use ASi V2 component. They use extended addressing. (i.e., use two banks of addresses).

Hence  a Primary ASi V2 is mandatory and hence the TSXSAY100 must be replaced by TSXSAY1000.

Detailed information:

If we manage a secondary ASi V2 with a primary ASi V1 there are some restrictions as listed below:
Only a maximum of 31 secondaries is supported.
V2 secondaries have the option to address 1-62 instead of 1-31 (or to be more
exactly 1a-31a and 1b-31b), while a V1 device will use both addresses
(a+b) as they "don't know about the 'b' side."

In case of a periphery fault :
The secondaries are not inhibited ( in our offer )
the primary can ’t manage the periphery fault information from the secondary

=> The PLC can ’t differentiate an open contact and an input supply short-circuit.
=> The operator is not warned of output short-
Typically a primary V1 cannot handle extended addressing.
From a V2 secondary device point of view, typically the profile(s) are not supported by the V1 primary.

Hence the recommendation to use a TSXSAY1000 which is a ASi v2 primary, with a TeSys LF3MP06EU
