Re-upload the project to the controller.Ensure that any Data Blocks that need to be accessed have "Optimized block access" disabled.Ensure that any Data Blocks that need to be accessed have the "Accessible from HMI" box enabled.During the channel configuration, specify the OPC UA Server Endpoint matching what was configured in TIA Portal for your S7-1500 controller. The channel corresponds to the OPC UA session to the S7-1500 UA server.
NI OPC SERVER S7 1200 DRIVER
(The Siemens TCP/IP Ethernet driver does not currently support the use of a password.) Check the "Permit access with Put/Get communication from remote partner" check box. Add a new channel in the TOP Server Connectivity section using the OPC UA Client driver. Ensure that the "Full access (no protection)" radio button is selected. On the General Tab of the Properties page select Protection. Open the PLC project in the S7 TIA Portal software.To do this perform the following steps in TIA Portal: įor TOP Server to be able to communicate, the S7-1200 and S7-1500 controller using Siemens Native Ethernet must be set to permit access from the server. The TOP Server OPC UA Client Driver, which is part of the TOP Server Siemens Plus Suite, can connect to that OPC UA interface, which provides additional capabilities that are not available via Siemens Native Ethernet. The S7-1500 PLC also supports an optional OPC UA server interface in the PLC. Older versions 5.12 and 5.13 of TOP Server support Siemens S7-1500 devices using the S7-1200 model. Starting with Version 5.14 or newer (including the current V6 family), TOP Server added a new device model in the S7 Ethernet driver for the S7-1500. TOP Server can communicate using this Siemens Native Ethernet protocol using the TOP Server Siemens Suite S7-Ethernet driver, with some limitations described later in this tech note. The S7-1500 has an embedded Ethernet port which supports the S7 Communications over Ethernet protocol.
