Overview
This section covers aspects of configuring ACM to communicate to Prosoft Enhanced Modules, MVI56E or MVI69E.
Security Options
As of release 7.1.268, ACM does not support the security feature of the enhanced Prosoft module in which an operator ID and password are supplied to log in to the module. Even if additional operators or passwords have not been configured on the device using EAFC Manager, the default log in still requires a password. This feature must be disabled on the Network Server port or serial port that is used for ACM communication.
If the feature is not disabled, any time ACM sends a Modbus message to the module, it will respond with a Modbus exception log entry of “Illegal Data Value”. This is something to look for if communications do not work with a newly installed module.

- Next select the On-Line\Operator Database, then click the button to Connect As Administrator. Operator 3 is the Default Administrator.
- Select the Authorization Defaults tab then set the Default Operator Number of the port ACM will use to ‘3’. In this example, ACM will connect via Network Server 1.
- Next click on the Privilege Waivers box for the same port in order to disable the password requirement.
- Enable Option Zero, Password Not Required. Click OK to save.
- Back on the Operator Database screen click Apply, then Done. That completes the Security set up for the module. This must be done for every enhanced module in your system that ACM will communicate with.
ACM Configuration
The remainder of this document assumes familiarity with the ACM configuration process and the objects used to define devices, meter, archives, etc. It will step through the process of creating a Prosoft device with one orifice gas meter with hourly EFM collection. The process to create additional meters, or a different type of meter, is the same, only the registers addresses will differ.
