Chapter 16 – Firmware Revision History
Fix: Issue with FCM Mapping report for SCS I/O Board. The mapping of the ports types were
incorrect.

Fix: Additive PID loop logic. If the math for the output went above 24 mA, it would roll
over to 0 mA. In the worst case scenario, the output would rollover to 0 mA and then
continue to increase again until finally settling at approximately 12 mA.
The logic will now bound the output to 20 mA and leave it there until the output of
the PID loop drops below 20 mA.
Enhancement: The error calculation in the PID loop has been changed from
(target_pulses - delivered_pulses) to (target_volume - delivered_volume).
This allows for a more gradual change in the relationship between the
response time and the setting of the P-Factor in the PID loop calculation.
For example: with the default settings for the I-Time and the D-Time. The
rise time (time it takes to go from 4 mA to 20 mA) when P=1.000 was 11
seconds, now it is 22 seconds (takes longer to respond). Anyone using this
functionality in previous firmware versions will need to adjust this
parameter after upgrading. You will likely need to increase the setting of
the P-Factor.
Fix: FCM comm loss when checking for SD card on bootup. Only an issue when SD card was
not present.
05/23/2017 MSH
Increased firmware version to x.31.36
Allow for additive pacing based on Gross/Net/Mass delivered.
Calculate additive PPM in Alibi Log based on additive Delivery Type.
06/08/2017 MSH
Remove delivered pulses from additive diagnostic screen for analog additives.
Fix additive calibration screen for analog additives.
06/12/2017 TF
Added a new parameter for each alarm called Require Authentication. If this parameter
is enabled, the MultiLoad will force one of the users to login when attempting to clear
an alarm. It will also log the username of the person who cleared the alarm. Usernames
and password must be configured at the RCU General Setup screen. The alarm level must
be set to REMOTE or higher for this functionality to work.
Fix (SCS Only): valve control alarm being thrown while in the divert state.
Added support for no flow control valve. Repurposed the parameter "Analog Valve Control"
at the meter level. This parameter is now called "Flow Control Valve Type", and can be
set to DIGITAL, ANALOG, or NONE. If set to
NONE, the following parameters will be ignored:
- Flow Start Delay
- Low Flow Start Volume
- Low Flow Restart Volume
- 1st Stage Trip Volume
- 2nd Stage Trip Volume
Increased the max input for 4-20mA Pressure value from 4000.00 to 9999.99
Fix (UAP Only): Issue with reading MAC address at high temperatures for a particular
serial flash chip.
08/02/2017 TF
Increased the firmware version of the legacy line to x.31.37
Firmware Version 3/4.31.37
