Siemens

The Siemens driver will communicate with Siemens S7 control device family.

General Settings

. Host/IP: Insert the Route Path of the controller

. Enable: Activates or deactivates the Driver Document

- TRUE: The document will be always activated

- Condition: Activates the document whenever the condition is fulfilled

- FALSE: The document will never activate

Siemens

. Model: Choose the PLC model: S7_200, S7_300, S7_400, S7_1200 and S7_1500

Read

. Trigger: If checked, will read all the inputs every time a configured tag changes its value. Select the desired tag to use as a Trigger in the TextBox beside it.

. Refresh Time(ms): If checked, will read all the inputs every specified time, in milliseconds.

Write

. Trigger: If checked, will write all the inputs every time a configured tag changes its value. Select the desired tag to use as a Trigger in the TextBox beside it.

. Tag Changed: If checked, will write an input every time its linked tag (of the Tag List) changes.

Tag List

When opening a Driver Document, it will display Driver options in the Ribbon where it is possible to create and delete Driver Items.

A Driver Item is what links a Tag from SmartView to an Input or Output of a Controller.

Once a new Driver Item is inserted, the user will have four fields to configure:

. Tag: Write the Tag that is going to be associated with the specific address

. Address: Write the Address, for example the address "DB3.DBX0.0" register type is Data Block and the format is Bit, see all the types below:

- X: Bit

- UB or SB or B: Byte

- UW or SW or W: Word

- UD or SD or D: DWord

- F: Float

- ST: String

The driver supports the following registers.

Register Type	Write	Read	Bit	Byte	Word	DWord	Float	String
Column1	Column2	Column3	Column4	Column5	Column6	Column7	Column8	Column9
M (Flags)	✔	✔	✔	✔	✔	✔	✔	✔
SM (Special Flags)	✔	✔	✔	✔	✔	✔	✔	✔
T (Timers)	✔	✔	✖	✖	✔	✖	✖	✔
Z or C (Counters)	✔	✔	✖	✖	✔	✖	✖	✔
I or E (Inputs)	✖	✔	✔	✔	✔	✔	✔	✔
A or Q (Outputs)	✔	✔	✔	✔	✔	✔	✔	✔
DB (Data Blocks)	✔	✔	✔	✔	✔	✔	✔	✔

Example:

We configured the simulation of communication with SmartView and Siemens S7_1200.

01. Create newtag1, integer in the tags document.

02. Create Siemens folder in Driver.

03. Create Driver1 document inside Siemens folder.

04. Select S7_1200 in Model.

05. Chech RefreshTime(ms) in Read

07. Write newtag1 on Tag cell

08. Write MW0 on Address cell

09. Run the application

Here is an example of a configured document with Data Block Register type:

Here is an example of a configured document with Input Register type:

Here is an example of a configured document with Output Register type:

Here is an example of a configured document with Memory Flag Register type:

Here is an example of a configured document with Special Memory Flag Register type:

Note: To communicate with the PLCs s7-1200 and s7-1500 families,it needs special configuration. See S7-1200/S7-1500

Note: To use String format in the address, it needs to specify the length. For example:

"QST0.3" is a Register Type Output with the format String with length 3.

If the value of a tag string has more than 3 characters(length), then the value passed to the driver will be the first 3 characters the tag value.
