FC 241 - DSOE Data Interface

The DSOE data interface block provides interface to Harmony block sequence of events data (HSOE) or the INSEM01 Sequence of Events module to access the time-stamped data (DSOE) produced by the IMSET01 Distributed Sequence of Events Time module and the IMSED01 Distributed Sequence of Events Digital Module.

 

NOTE: This function code is supported by the HAC, BRC-100, and IMMFP11/12 controllers.

 

This function code is required for both the controller and INSEM01 module to configure a distributed sequence of events system.

241.1   Explanation

 

241.1.1  Specifications

 

S1

Expander bus address configured by means of dipswitches on the IMSET01 module. This specification is not used by the HAC controller and must be left at the default value.

 

S2

Maximum number of event records, produced by a Harmony I/O block or any of the IMSED01 or IMSET01 modules connected to the controller, that is possible to store before a buffer overflow occurs.

 

S3

Block address of first digital event interface (function code 242), I/O device definition (function code 221), or gateway (function code 227).

 

When using a Harmony rack DSOE, function codes 241 and 242 form a linked list that describes the IMSED01/IMSET01 configuration for the controller. Function code 241 must be at the head of the list. This specification is used to point to the first IMSED01/IMSET01 descriptor (function code 242).

 

When using a Harmony block HSOE, function codes 241 and 221 form a linked list. Function code 241 must be at the head of the list. This specification is used to point to the first I/O device definition (function code 221).

 

When using a gateway with HSOE, function codes 241 and 227 form a linked list. Function code 241 must be at the head of the list. This specification is used to point to the first gateway (function code 227). Specification S3 linkage to the gateway (function code 227) is supported only in the BRC-100 and BRC-200 controllers.
