Firmware Options
Choose firmware with the features needed for the applica-
tion:
• Standard—includes closed-loop PID control, auto-tune,
alarms, job memory and failed sensor detection.
• Extruder— includes the standard firmware features, with
PID control specifically adapted for plastic extruders.
• Ramp and Soak—includes the standard firmware features
with the addition of ramp and soak and process variable
retransmit. Each channel can be configured for standard
PID control or ramp and soak operation. Unused control
outputs on any channel can be configured for retransmit.
• Enhanced Features— includes the standard firmware
features with the addition of process variable retransmit,
remote analog setpoint, cascade control, ratio control
and differential control algorithms. Each channel can be
configured for standard PID control or one of the other
control algorithms. Each channel of cascade control or
remote analog setpoint requires two controller channels.
Unused control outputs on any channel can be configured
for retransmit.
Because the MLS300 has no onboard analog outputs,
applications that use process variable retransmit typically
require one SDAC module per retransmitted signal.
Input Module Options
Choose the input module appropriate for the application:
• AIM316 and AIM332 provides screw terminations for
16 or 32 sensors
• CIM316 and CIM332 provides DB-50 connector
terminations for 16 or 32 sensors in a compact size
