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.
...
To disable the feature, start the EAFC Manager software and set the Communications\Local Port Settings to connect to the module. After connected, select the Communications\Login Module and log in with an Administrator operator account.
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.

|---|---|---|
| ||
| If ACM will be used to do gas analysis downloads to an Enhanced Prosoft module, first read the Gas Analysis Writes and Flow-Cal®FLOWCAL SCADA Request Service in order to properly know how to name and configure ACM meter objects. |
...
| Info | ||

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.
...
Once the Meter Configuration object is complete for Meter1, the objects for the other meter runs can be easily created by copying the Meter Configuration object, renaming it, then changing the addresses in the Advanced Configuration grid. On the Prosoft module, each subsequent Meter’s configuration registers are offset from the previous meter by a value of 1000, i.e., all of Meter1’s configuration registers are in the 8000 range, Meter2 in the 9000 range, Meter3 in the 10000 range, etc.

Archive Object
On the Meter Runs tab of the device object, create a new Archive Object for the Hourly Archive property. Set the new Archive Object to be Periodic with a period of 60.
...
On the Field Configuration tab of the Archive Field object, click the Edit Configuration button. For each field defined in the archive in EAFC Manager, you will need to add the corresponding field record in this object. Each field in the archive must be included even if the field will not be used in reporting or if the field is an empty slot, i.e. <available>. The Position property must be correct and match the order in EAFC Manager.

Combining Totalizer and Residue
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. |
| Info | ||
|---|---|---|
| ||
If a scale string is configured to be 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 manager as described in other documents. Obtaining values from Flowcal is also supportedFor guidance on using ACM to write gas analysis data to the module, refer to the Gas Analysis Writes section of the user guide.
The following GC values are supported for download:
