Group 32: SUPERVISION

This group defines supervision for up to three signals from
DATA. Supervision monitors a specified parameter and energizes a relay output if
the parameter passes a defined limit. Use
relay and whether the relay activates when the signal is too low or too high.
Code Description
3201 SUPERV 1 PARAM
Selects the first supervised parameter.
• Must be a parameter number from
DATA.
• 100 =
NOT SELECTED
• 101...159 – Selects parameter 0101...0159.
• If the supervised parameter passes a limit, a relay output is
energized.
• The supervision limits are defined in this group.
• The relay outputs are defined in
OUTPUTS (definition also specifies which supervision limit
is monitored).
LO ≤ HI
Operating data supervision using relay outputs, when LO≤HI.
• Case A = Parameter 1401
2, etc.) value is
OUTPUT
for monitoring when/if the supervised signal exceeds a
given limit. The relay remains active until the supervised
value drops below the low limit.
• Case B = Parameter 1401
2, etc.) value is
OUTPUT
Use for monitoring when/if the supervised signal falls
below a given limit. The relay remains active until the
supervised value rises above the high limit.
LO > HI
Operating data supervision using relay outputs, when LO>HI.
The lowest limit ( 3203) is active initially and remains active
HI
until the supervised parameter goes above the highest limit
( 3202), making that limit the active limit. That limit remains
LO
active until the supervised parameter goes below the lowest
limit ( 3203), making that limit active.
HI
• Case A = Parameter 1401
2, etc.) value is
OUTPUT
Initially the relay is de-energized. It is energized whenever
the supervised parameter goes above the active limit.
• Case B = Parameter 1401
2, etc.) value is
OUTPUT
Initially the relay is energized. It is de-energized whenever
the supervised parameter goes below the active limit.
3202 SUPERV 1 LIM LO
Sets the low limit for the first supervised parameter. See
3201 1
SUPERV PARAM
3203 SUPERV 1 LIM HI
Sets the high limit for the first supervised parameter. See
3201 1
SUPERV PARAM
3204 SUPERV 2 PARAM
Selects the second supervised parameter. See 3201
3205 SUPERV 2 LIM LO
Sets the low limit for the second supervised parameter. See 3204
3206 SUPERV 2 LIM HI
Sets the high limit for the second supervised parameter. See 3204
