The protocol specification explains that the qualifier value for these commands
should be configured as:
Bits Value
Description
0 Not
Used
1
Threshold Value (Deadband)
2
Smoothing Factor (filter time constant) – Not Supported
3
Low Limit Transmission of Measured Value
4
High Limit Transmission of Measured Value
1 to 6
5..31 Reserved
0 No

7
1 Change

8
1
Not in Operation
For the 4205/5205-TS-104S-PDPS module, the Low Limit and High Limit
parameters cannot be changed by command, because these values are
calculated as follows:
Low Limit = (LAST REPORTED VALUE) – Deadband
High Limit = (LAST REPORTED VALUE) + Deadband
These commands must be sent to a specific Information Object Address. The
4205/5205-TS-104S-PDPS module associates each monitor measured point with
a parameter point through the following configuration parameters:
M_ME_NA Parameter Offset : 2000 #M_ME_NA IOA offset for parameter data
M_ME_NB Parameter Offset : 2000 #M_ME_NB IOA offset for parameter data
M_ME_NC Parameter Offset : 2000 #M_ME_NC IOA offset for parameter data
Example:
If the following monitored measured points are configured:
[M_ME_NA_1 104]
#
# Default
# Point # DB Address Group(s) Deadband IV DB Bit
# ------- ---------- -------- -------- ---------
