Parameter Identifier Description
Power Output
value
W If Manual Control is not selected, may be read
only (Type 2 message). If Manual Control is
selected, may be read (Type 2 message) or
modified (Type 3/Type 4 message sequence).
Output 1 Power
Limit
B May be read (Type 2 message) or modified (Type
3/Type 4 message sequence). Defines power limit
for Output 1.
Output 1 Cycle
Time
N May be read (Type 2 message) or modified (Type
3/Type 4 message sequence). NOTE: Value must
be a power of 2 in the range 0.5 - 512 (i.e. 0.5, 1,
2, 4, 8 etc.). For a Relay Output, cycle time should
be as large as possible (whilst remaining
compatible with the process control requirements)
in order to maximise relay life. For an SSR Output,
the cycle time may have a lower value (and thus
satisfy the requirements of a fast-changing
process variable e.g. flow or pressure).
Output 2 Cycle
Time
O May be read (Type 2 message) or modified (Type
3/Type 4 message sequence). NOTE: Value must
be a power of 2 in the range 0.5 - 512 (i.e. 0.5, 1,
2, 4, 8 etc.). For a Relay Output, cycle time should
be as large as possible (whilst remaining
compatible with the process control requirements)
in order to maximise relay life. For an SSR Output,
the cycle time may have a lower value (and thus
satisfy the requirements of a fast-changing
process variable e.g. flow or pressure).
Recorder Output
Scale Max.
[ May be read/modified by a Type 2 message or a
Type 3/Type 4 message sequence. Corresponds to
Input Scale Max. with decimal point position as for
input. If less than Recorder Output Scale Min.
sense of recorder output is reversed.
