5.1.1 Functional Specifications
The MVI56-104S module accepts data read/write commands from a master/client
on the network. In addition, the module can be configured to generate unsolicited
messages in either a spontaneous or cyclic fashion.
The module has 4000 words of user defined internal register space that are
accessible to the protocol driver and to the ControlLogix processor memory. Any
of the supported database types can be individually located (within the total
database size limit of 4000 words) and each database point is mapped within the
module and can be assigned to one or more Groups. The supported database
point types are:
Database Type Description
M_SP_NA Monitored single-point database
M_DP_NA Monitored dual-point database
M_ST_NA Monitored step-point database
M_ME_NA Monitored normalized-point database
M_ME_NB Monitored scaled-point database
M_ME_NC Monitored short-float point database
M_IT_NA Monitored integrated total database
C_SC_NA Command single-point database
C_DC_NA Command dual-point database
C_RC_NA Command step-point database
C_SE_NA Command normalized-point database
C_SE_NB Command scaled-point database
