Points Used on Simatic S7 Scanners
Simatic S7 Scanners can support the Analog Points and Digital Points.
You configure the Simatic S7 points on your system using the Simatic S7 Analog Point Form, or the Simatic S7 Digital Point Form, as appropriate.
Each Form has several tabs.
You define the Area of memory that each Scanner is to scan using the relevant fields on the Scanner Form (see Configure the Scan Properties). You then define the location of the specific items of data with which each point is associated and the Scanner that is to scan that data, using properties on the Simatic S7 tab on each Point Form.
For information on configuring properties on the Simatic S7 tab, see Configuring Analog Points, or see Configuring Digital Points.
For information on configuring properties on the <Point Type> tab, see the appropriate reference below:
- Analog Point—see Defining Analog Point Details in the Geo SCADA Expert Guide to Core Point Configuration
- Digital Point—see Defining Digital Point Details in the Geo SCADA Expert Guide to Core Point Configuration.
Use the Enabled check box on the Control tab to specify whether a particular point is used as an Input point or an Output point. An Input point is used to retrieve data from a read-only memory area on a Simatic S7 PLC, whereas an Output point is used to write data to a read/write memory area:
- For Geo SCADA Expert to read data from a read-only memory area (such as an Input Register or Analog Inputs area), you need to clear the Enabled check box on the Point Form’s Control tab. This sets the point to be an Input point and makes the Control tab settings unavailable.
- For Geo SCADA Expert to write data to an Output Register, Analog Output, Flag/Marker, Special Memory or Data Block, you need to select the Enabled check box on the Point Form’s Control tab. You also need to configure the settings on the Control tab.
For information on configuring properties on the Control tab, see:
- Analog Point—see Define the Control Settings for an Analog Output Point in the Geo SCADA Expert Guide to Core Point Configuration
- Digital Point—see Define the Control Settings for a Digital Output Point in the Geo SCADA Expert Guide to Core Point Configuration.
For properties on other tabs, see Tabs on Point Forms in the Geo SCADA Expert Guide to Simple Drivers.
