NOTE
5.8 Retransmission Group (G.RET)
This parameter sets the type of retransmission operation to use. Options are PV, SP, MV,
and LPS. See notes below for an explanation of the retransmission types.
The default setting is PV.
PV
These parameters are used to scale the retransmitting output. They set the high and low
limits for th e retransmission output scale, as shown below. The retransmitting outputs will
transmit 4 mA at th e low limit (RETL) and 20 mA at the high limit (RETH) values. These
limi ts are used when the retransmission type is set to PV or SP.

PV and SP Type Retransmission Scale
PV type retransmits based on the input value, SP retransmits based on the set point value.
