APPENDIX C - FUNCTION CODE DEFINITIONS
INTRODUCTION
The IMASI03 Universal Analog Input Slave Module is config-
ured and controlled through function blocks configured on the
master MFP. This section describes the three function codes
that support the IMASI03. They are FC 215, FC 216 and FC
217.
All specifications in function codes 215, 216 and 217 associ-
ated with the IMASI03 may be changed during on-line configu-
ration. When changes are made to the input channel
parameters (FC 216), the channel will hold the last value with
status unchanged for a short period. This hold time is based on
the number of channels that were changed during on-line con-
figuration, as well as the resolution specified in the function
code 216 blocks for that channel. Plan on a hold time of four
seconds (worst case) for each function code 216 changed dur-
ing on-line configuration.
The function code information in this appendix is for reference
only. Refer to the
Function Code Application Manual,

for current information on the function codes.
ENHANCED ANALOG SLAVE DEFINITION FUNCTION CODE (FC 215)
This function code is used to define an analog slave module to
the MFP.
The Enhanced Analog Slave Definition Function Code (FC215)
defines the common specifications for the IMASI03 module.
Individual input function code 216 blocks are linked to this
block to define the channels available on an IMASI03. Function
code 215 uses 30 bytes of NVRAM and 206 bytes of RAM mem-
ory in the MFP module.
This function block has three outputs. The first represents the
cold-junction reference input in degrees C from the analog
slave input module termination device. The second output is a
Boolean value representing the overall status of the slave mod-
ule. The third output gives the actual scan cycle time in sec-
onds for all of the active inputs on the slave.
