Re: [foxboro] SOE resolution

The SOE function provided by the EVENT block supports only certain FBMs
and none of the cluster I/O modules.

Table 1 Discrete FBMs and their SOE Capabilities
FBM Type   EVENT/ECB6 V8    Description
FBM207     Y          Y     Contact or DC In (16)
FBM217     Y          Y     Contract or DC In (32; group isolated)
FBM07      Y          N     Contact or DC In (16)
FBM12      Y          N     FBM07 Expander
FBM20      Y          N     240 VAC In
FBM21      Y          N     FBM20 Expander
FBM24      Y          N     Contact or 125V DC or Ext Power (16in)
FBM25      Y          N     FBM24 Expander

There is no SOE support for any Cluster I/O (FBC) module or any other
FBM master or expander modules than those listed.

Alex,
thanks for your answer, but i was reading in B0193AX and there are two=20
parameters: FPE06 and FPM06 for filter functions and the minimum value=20
specified is 4 msecs, then i think the resolution should be greater than
4=20
msecs ... am i wrong ?
Regards,
Miguel
