WARNING

This command should only be used when it is necessary to

perform the above tests. Use of this command in normal

operation can result in loss of data.

PV Retransmit Primary Loop Number (81)

This parameter speciﬁes the primary loop number for obtaining the

process variable (PV) from the current loop or another loop. Setting this

to 0 disables PV retransmit for the loop.

• Range: 0 (none) to MAX_CH.

• Default: 0 (none).

PV Retransmit Maximum Input (82)

This parameter speciﬁes the maximum Process Variable input allowed

for PV retransmit calculation. This value must not be lower than the

minimum input (command 84).

• Range: –999 to 9999 (depending on precision in primary loop).

• Default: 14000 (1400°F) for a J-type thermocouple.

PV Retransmit Maximum Output (83)

This parameter speciﬁes the maximum output (%) allowed for Procedss

Variable retransmit calculation. Once speciﬁed, the output will not

exceed this percentage. This number must not be lower than the

minimum output (command 85).

• Range: 0 to 100.

• Default: 100%.

PV Retransmit Minimum Input (84)

This parameter speciﬁes the minimum PV input allowed for PV

retransmit calculation. This number must not be higher than the

maximum input (command 82).

• Range: –999 to 9999 (depending on precision in primary loop).

• Default: –3500 (-350°F) for J-type thermocouple.
