OPD: Operator dialog with electronic signatures

OPD: Report

OPD enables the addition of comments and electronic signatures for APL operating commands, e.g. mode change or setpoint adjustment

The operator dialog (OPD) software simplifies the interaction between operating personnel and process control system. As a powerful operator tool, it facilitates control of the process and provides complete proof of all manual operations, which is essential for a validated batch system.

OPD software is based on SIMATIC PCS 7 now also supports the WebNavigator. It uses the SIMATIC logon for user verification and electronic signatures. It therefore complies with the validation requirements according to 21 CFR Part 11 and other statutory directives.

The OPD is similar in design and functionality to the APL library. Each OPD message can be configured with text, operator comment, process values, operating values, option boxes, checkboxes, and electronic signatures.

Note:

OPD can be used in combination with SIMATIC PCS 7 V8.x and V9.0.

Application

Operator interaction in an SFC phase

An OPD can be used in an SFC phase. The simplest interaction is a request to the operator to confirm an OPD message before progressing to the next step of the phase. A second application example is a request to the operator to select one of two storage tanks. Electronic signatures may be necessary in both cases.

Operator interaction between two SFC phases

At the batch level, OPD can also be used for operator interaction between two separate SFC phases. For example, the operator can be requested to select between different technical equipment which require separate subsystem assignments.

Operator interaction for event-based actions

OPD can also be used for event-based actions. One example is the request to an operator to acknowledge an OPD message before opening a valve, closing a pump or changing alarm limits.

Audit Trail

The entire operator interaction is stored in the form of WinCC messages and can be easily incorporated into SIMATIC BATCH standard reports. In addition, they can be transferred to any MES system that supports long-term archiving of SIMATIC PCS 7 process data.

Operator dialogs

The operator dialogs can be easily edited with any spreadsheet program, such as Excel.

Each OPD message can have the following content:

• 1 text message (1 060 characters)
• 1 operator comment (1 060 characters)
• 0 to 6 process values (string or real)
• 0 to 6 operator inputs (string or real)
• 0 or 1 option group with up to 10 option boxes
• 0 or 1 checkbox with up to 10 checkboxes
• 0 to 2 electronic signatures
