2 THEORY OF OPERATION

The Programmable Serial Interface Card (PSIC) has 2 ports which can be configured for
RS-232, RS-422/RS-485 Half Duplex or RS-422/RS-485 Full Duplex communications
with external devices. For communications with the F250 Precision Thermometer devices,
any mode may be used. The driver supports only one F250 device per port. Specifically,
the devices cannot be multi-dropped.

The DeltaV Serial Card Driver functionality will be as follows.

1. The driver will be flashed into the PSIC.

2. The driver will run in Master mode only and be responsible for sending commands to
the F250 units. The F250 will respond with temperature reading information, which will be
reported to DeltaV in dataset registers.

3. The two ports of the PSIC work independently, each connected to a single F250 unit.

The following shows PSIC connectivity with F250 Precision Thermometer devices.

4.2 Device Configuration

Specify devices, as shown above. There will be one device under each port.

4.3 Dataset Configuration

MYNAH Technologies ▪ 504 Trade Center Blvd ▪ Chesterfield, MO 63005 ▪ Telephone [phone] ▪ Fax [phone]

4.1 Port Configuration

First, enable the port. Then click on the Advanced Tab and Master mode. Slave is not
supported. Specify the retry count, message timeout value in milliseconds, and message
delay time. In most cases, you can leave these at their default values. Next, click on the
Communications Tab and specify the Port type. The Port type will be RS-232. In general,
RS-232 will be used for F250 communications, unless there are distance limitations. If the
F250 is more than 50 feet from the PSIC, RS-485 should be used. Lastly, select the Baud
rate, Parity, Data bits and Stop bits parameters; these must match the F250 settings.

Datasets contain the F250 information, and must be configured as described in Table 3.

4.3.1 Data Direction:

The Data Direction for should always be defined as Input.

4.3.2 Output Mode:

Output mode and Read back items are not used. These should be left as default.

4.3.3 DeltaV Data Type:

All datasets will be configured as type Floating Point.

4.3.4 DeviceDataType

The following device data types are available. Only one configuration should be chosen.
For example if Configuration 1 is desired only 1 dataset is required. If Configuration 2 is
desired then two datasets are required one with DeviceDataType 1 and the other with
DeviceDataType 2.

Table 4

DeviceDataType Description

0 Configuration 1 – Read Only the currently selected PRT.
1 Configuration 2 – Read each device attached to Input A
2 Configuration 2 – Read each device attached to Input B
3 Configuration 3 – Read A, B, and A-B Differential

4.3.5 Data Start Address and Number of Values

The Start Address for each dataset is not used and can be left as default 0. The Number of
values for Configuration 1 is 1 register. For Configuration 2, the number of values depends
on the number of attached devices to each dataset. Configuration 3 requires 3 Registers.

4.3.6 Special Data

The following device data types use special data registers to specify additional parameters
required for reading from the F250:

5 Operational Check

5.1 Scope

The following sections provide some assistance to ensure the interface is working

properly.

5.2 Verify Hardware and Software Version Number

To begin the DeltaV Diagnostic tool select Start-> DeltaV-> Operator-> Diagnostics. In

The following information will be displayed:
: : :
HwRev Hardware Revision 1.10 (or later)
SwRev Software Revision 2.3 (or later)

The user can verify that the F250 driver has been installed using the DeltaV Diagnostics
tool. The Diagnostics tool will show the Hardware Revision No. (HwRev) and the
Software Revision No. (SwRev).

the Diagnostics tool expand the Controller, I/O and then double click on the
Programmable Serial Interface Card that has the driver installed.

5.3 Verify Configuration

• Verify port configuration: The serial port must be enabled. User needs to make sure

communication settings such as baud rate, parity, and number of data bits match the
field device settings.

• Verify dataset configuration: The datasets configured must be as shown above.

5.4 Verify I/O Communication With Control Studio

User can create I/O modules in the control studio to verify correct values are being
written out. An example module is shipped with the distribution. This module shows
methods for writing text to the datasets and also how to handle time.

5.5 Using Diagnostics

• Verify PSIC communication: Select the PSIC on Diagnostics and press the right

mouse button. Select Display Real -Time Statistics from the drop down menu. If the
Programmable Serial Interface Card is functioning then the user will see the Valid
Responses counter and the Async and/or Sync Transactions counters incrementing.
There will not be any error counting up.

POWERFUL SOLUTIONS FOR DIGITAL PLANTS

• Verify port statistics: Select the Port on the Programmable Serial Interface Card and

press the right mouse button. Then select Display Port Statistics form the drop down
menu. Verify that the port communications statistics are being displayed properly
and are counting as expected for the protocol’s functionality.

• Verify dataset values: Select a dataset and press the right mouse button. Select

View Dataset Registers from the Drop down window. Verify that the dataset values
are displayed as expected.

5.6 LED Indication

The Yellow LED for the port should be on solid when all communications on that port are
valid. The Yellow LED should be blinking if there is some valid communications and
some communications with errors on that port. The Yellow LED should be OFF if there
are no valid communications on that port.

6 DeltaV–Field Device Electrical Interface

The electrical interface between DeltaV and field devices conforms to the RS-232 and
RS-422/485 standards.

Each PSIC has 2 ports, which function independently. The distance between the serial
card and the field device can be as much as 5000 feet, per the RS-422/485 standard.
When using RS-232, the distance is limited to 50 feet. Section 6.1 shows the pin
assignments for the PSIC serial terminal block.
