When opening multiple projects with the network configuration tool, a window is displayed, Windows are multiple items in the project. If opening is included in multiple items in a project and select View → Multiproject, you can also get this window. This window shows the multiple items in the project and has grouped network between projects. Double-click Select items can be further processed.Projects typically include the communication links between the variousworkstations. If the project as a single multiple-project, or a project includes multiple projects already in existence, and these connections can be a mix and match.Multiple items in a network configuration1. Combination networkFirst, MPI, PROFIBUS and industrial Port-au-Prince network together, if is going to be a combination of subnet have the same subnet ID. Select subnet, network configuration tools, you can use Edit → set Object Properties.With the Multiproject File → → Adjust Projects, you can call in the SIMATIC ManagerWizard to open multiple projects, which can support the match. In the network configuration, use Edit → Merge/unmerge subnetworks → ... Get dialog window.Select the network type, click on "Run (run)" button, get multiple subnet corresponding to the selected type in the project. You can now select items of each network into multiple networks. You can use a dialog box to remove networks from the network.In a multiple projects, you can create several different types of networks. This Subnetwork properties determined by the first to add subnet, or by clicking "Select (select)"button the selected networks. Click "OK" or "import (input)" responds to the set. Aspart of the multi network subnet, use different symbol recognition in the SIMATICManager.2. Combined connectionConfiguration in a separate project and connection to communicate with another partner in the project, can be a combination of multiple projects. If the configurationin a separate project when, in the window "Insert new connection (insert a new connection)" select partner "In unknown project (unknown)", in the window "Properties-S7 connection (characteristics of-S7 connection)", enter connection name (reference).In different projects in connection with the same connection name can be automatically combined.In the SIMATIC Manager, if you click the "Merge connections (combination connection)" and "Execute (execute)", can be represented by a match Wizard to complete this task. With the same connection name (reference) connected together.In the network configuration, can also be combined with the "undefined partner" connection. Select Edit → Merge connections, get a fully configured the connection dialog box. In each "Connections without connection partners (not connected with connection partners)" window, select a connection, and then select "Possible connection partners (possible connection)," then click "Assign (distribution)". The assigned connection listed in the lower window "Assigned connections (allocatedconnection)", and then "Merge (combo)" combined connection. Assigned to the connection attribute is local to the project that is currently open module feature, whencombined can modify connection properties.3. Configuration itemsNetwork mix after the configuration items. Its connections within the process and project the same increase is the partner of the project description.

Siemens S7-200PLC Counter Area (C)

In the S7-200 CPU, the counter for the accumulated number of pulses from the input terminal or internal components sent. It has up counter, down counter and up / down counter 3 types.Due to limitations counter frequency scan cycle, when the need for high-frequency signal can be counted when a high frequency counter (HSC).There are … Continue reading Siemens S7-200PLC Counter Area (C)

Siemens S7-200 PLC local variable storage area (L)

Local variables and variable storage memory is very similar, the main difference is that the local variables memory is partially valid, the variable memory is globally effective.Globally effective refer to the same memory can be used by any program (such as main program, an interrupt routine or subroutine) access to local storage areas and effective … Continue reading Siemens S7-200 PLC local variable storage area (L)
