Add and configure the I/O function blocks
Once the Hardware Configuration and Temperature transducer blocks have been configured, they
must be connected to input and output function blocks so that the I/O signals are available to the
Field Controller system.
Note!
• BA 022S/04/en, Function Block Manual, contains a general description of the function block
process, including the alarming and I/O options that have been omitted for simplicity here. It also
contains a detailed explanation of all function block parameters.
5.3.1
CHANNEL parameter
The connecting element between transducer and function block is the channel parameter. For the
Field Controller I/O modules, this is compiled according to the following hierarchy:
The value in the CHANNEL parameter is given by the value RSGP:
• Rack assembly address (R):
Each rack assembly has a unique address between 0 an 14 .
The rack assembly with the address "0" cannot be used by the I/O modules.
• Slot (S): Each rack assembly has four slots. One slot supports one I/O module.
Slots are numbered from 0 (first slot) to 3 (last slot).
• Group (G): Ordinal number of group in the specified I/O module
Groups are numbered from 0 (first group) to number of groups minus 1.
• Point (P): Ordinal number of I/O point in a group
I/O points are numbered from 0 (first I/O point) to 7 (last I/O point in the group)
9 means the whole group of points and is used when a module is connected to a MAI, MDI,
MAO or MDO function block.
Thus, a single I/O point in the Field Controller may be identified by specifying the rack (R), slot (S),
group (G) and point (P). As the CHANNEL parameter in the multiple I/O blocks (MIO) must specify
the whole group (8 points), the point must be 9, that means the whole group. For example:
• The CHANNEL parameter 1203 means rack 1, slot 2, group 0 and I/O point 3.
• The CHANNEL parameter for a MAI block 10119 means rack 10, slot 1, group 1 and
I/O point 9, i.e. the whole group.
Provided that the HC transducer block is configured before the CHANNEL parameter, the system
verifies that the I/O type configured in the HC block is suitable for block type. If the CHANNEL
parameter of the AI block accesses an I/O of a different type, the setting will be rejected during
download.
