Hi,
Could I get some suggestions on remote access methods for troubleshooting a Siemens panel (PLC 1215 with CP 1243-1)?

Hi,

Telecontrol Basic is the preferred solution for remote data acquisition and maintenance.

Another solution is to use SINEMA RC but it will provide limited functionality i.e. Remote Diagnostic access

One more alternative will be to use any IPSec VPN server.

All options require a public static IP address.

However, please note that a cost-effective alternative solution is available via LOGO! CIM module.

Regards,
