Example for Determining a Segment Fixed Register
Note: Custom map users must get segment addresses by printing a Modbus Register Report in HC Designer.
Note: To change the ramp value for Output #6 in segment #5 of setpoint scheduler #2, the register address
is determined as follows.
Step 1: Use Table 6-1 to determine the start address for scheduler #2’s segments. The value is 6C00 Hex.
Step 2: Calculate the offset address for segment 5 in a schedule. This is calculated as:
Segment offset address
=
(segment number – 1) * 48
=
(5-1) * 48
=
192 or C0 Hex
Step 3: Use the table above to determine the register offset for Output #6 ramp value. The value is 16 Hex.
Step 4: Calculate the address by adding the results of steps 1, 2, and 3 to determine the register address.
Register address
=
Schedule #2 segment start address
+ Segment 5 offset address
+ Output #6 ramp value register offset
=
6C00+ C0 + 16
=
6CD6
