VM overview
LOGO! Base Module uses VM (Variable Memory) as a local data communication interface for data exchange by means of connections/data-transfer configuration.
You can use LOGO!Soft Comfort with the Ethernet connections menu command following instructions in the Tools -> Ethernet Connections (0BA7 and later versions only) section to construct the network topology.
LOGO!Soft Comofort performs data exchange process as follows:
The server stores the required data into the VM area specified by the data connection and data transfer. This is defined as a "share" action in the following section.
The client unit reads the server's VM area and then updates the corresponding local VM area in its network process step.
After the local update, the circuit program in the client can use the information in the local VM originated from the Server.
|
Note
LOGO! 8.FS4 supports two types of connection, S7 and Modbus. LOGO! 0BA7 and LOGO! 0BA8 only supports S7 connection. |
Data type and VM address
The following illustrates VM addressing and data type usage:
Creating a parameter VM mapping
When you change a parameter value in the local VM, the value in LOGO!Soft Comfort changes accordingly. In this way, LOGO!Soft Comfort synchronizes information with the local VM in real time.
LOGO!Soft Comfort synchronizes the parameter values of a block to the specified VM in each LOGO! cycle. After the synchronization, LOGO! Base Module can use the VM to communicate with other SIMATIC devices. You can map up to 64 parameters in VM for each LOGO! Base Module in the Variable Memory Configuration dialog. For LOGO! 8.4 and later versions Base Module, 2048 bytes of VX area is extended for block parameter VM mapping.
The following screen is an example of the configuration dialog of parameter VM mapping:
The Block column lists the parameters for SFBs in the current program. The Parameter column provides a select list of the parameters of the corresponding block. The Type column displays the data type of the selected parameter. The Address column is also configurable. You can use it to identify the VM address used to save a parameter value.
The icon next to a parameter name indicates the property of this parameter:
|
|
The parameter value is a setting value and is writable. |
|
|
The parameter value is an actual value and is read-only. |
|
|
Although the parameter value is an actual value, you can still change the value. NOTE: Only the Counter parameter of Up/Down counter has such a flag. |
|
|
The parameter value is referenced from an actual value of another already-programmed function block. |
|
Note that if no flag appears, then the parameter value is a system value and remains read-only. |
|
Within the parameter VM mapping window, you can achieve the following tasks:
Select multiple record lines by pressing the Ctrl key or Shift key and clicking the ID of the desired line.
Insert a down line by pressing the Enter key on the last cell of the desired line.
Insert an up line by clicking the ID of the desired line and pressing the Insert key, or right-clicking the desired line to add a new row.
Delete a line by clicking the ID of the desired line and pressing the Delete key, or right-clicking the desired line to delete an existing row.
You cannot change the parameter type and must configure a unique address for each parameter. The range for a parameter address is from 0 to 850. If the value you input exceeds this range, inputs and outputs will be modified to certain VM addresses automatically.

The length (Byte, Word, or DWord) indicates the number of bytes in the VM area required by the parameter.
LOGO! Base Module can also share the time and date information with SIEMENS SIMATIC S7/Modbus compatible devices and HMI devices using VM addresses from 991 to 1002.
LOGO!Soft Comfort links the block parameters that you specify in the Variable Memory Configuration dialog with a VM address.
Not all of the VM area is available for configuration. LOGO!Soft Comfort reserves some bytes of the VM area. You cannot specify more than 64 parameters. If you attempt to specify more than 64, LOGO!Soft Comfort displays a failed operation message.
After the data transfer from a LOGO! Base Module to LOGO!Soft Comfort, you can view only analog values within the range of -32768 to 32767 on LOGO!Soft Comfort. If an analog value exceeds the value range, then only the nearest upper limit (32767) or lower limit (-32768) can be displayed.
