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.

- 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.

When creating a Prosoft device, there is no differentiation between Enhanced or older non-enhanced Enhanced modules as the type is determined automatically at runtimerun-time. |
On the Device tab, set the Register Set property to "Prosoft Enhanced Register Set". If connecting to the Prosoft module via a network port, enable the Modbus/TCP property.

Since the Prosoft has separate totalizer and residue fields for accumulators, ACM must be configured correctly to indicate these fields should be combined into one value. This is as simple as setting the Field Identifier property for both fields to be the same ID in the Archive Field Configuration Object. As show below, using the Tabular View, for Volume, both the totalizer field and the residue field have their Field Identifiers set to "Volume Record – Volume". Also note the data types of the two fields. The same configuration applies to the other accumulator fields.
| Info | ||

The Totalizer field is a 32-bit integer and the Residue is a 32-bit floating point. |

If a scale string is used, when defining the Totalizer field definition in ACM, the same scale string must be used on the Residue field. |

The ACM Prosoft module supports downloading gas analysis values to a Prosoft enhanced module. This is done through the ACM GCRequest GC Request manager as described in other documents. Obtaining values from Flowcal is also supported.
