ProSoft Connect

PLC Remote Access

ProSoft Connect is a secure, cloud-native service optimized for highly reliable performance. Connect allows you to establish communications with your machines anywhere in the world. Using Connect’s unique EasyBridge™ technology, your automation programming tools (such as Studio 5000, Unity Pro, TIA Portal, and many more) can talk directly to the automation devices without the need to setup IP routing or other complicated communications settings.

EasyBridge is just like being plugged in to the local switch. Connect uses standard security protocols including HTTPS and IPsec to ensure that your system is protected.

Technical Specifications


All communications with the ProSoft Connect service use HTTPS for site authentication and data encryption. Gateways are activated in Connect using a two‐step authentication. All gateway connections are initiated by the gateway to prevent a spoofed service from initiating a gateway connection. No user-installed software is required, which eliminates potential "watering hole" attacks and time‐consuming software patch maintenance for the user.

VPN tunneling

EasyBridge Secure Remote Access provides an AES256 encrypted Layer 2 VPN connection between the user's PC and the network connected to the Connect gateway. VPN uses the OS-native L2TP client with IPSec encryption to minimize possible security vulnerabilities of user-installed third-party VPN client software


The ProSoft Connect organization owner and project administrators can invite team members to join projects in the organization.


Projects allow the ProSoft Connect Organization Owner to group gateways and team members. Team members in a Project can only see the gateways, activities, and other team members in that Project. Two Projects are standard for each Connect Organization. Additional Projects are available by purchasing a Power User Plan.

Access Control

Access control for users is managed by the account administrator. Users are assigned rights to administer, connect and configure gateways, or to connect only.

Power User Plans

ProSoft Connect Power User Plans are ideal for system integrators and machine builders who rely on Connect to service their customers. Power User Plans increase the monthly EasyBridge data limits, number of concurrent connections, and number of projects making it easier to manage remote access for multiple end customers.

Ethernet/Cellular Connections

Outbound connections from gateways use HTTPS only. Client VPN connections use L2TP via ports 500, 4500 and 1701.

PC Client Software

User-installed software is not required for Connect. Connect is compatible with current versions of Chrome, Firefox and Internet Explorer 10 or later. EasyBridge uses the OS-native L2TP client software. Windows 7 or later is recommended.


ProSoft Connect works with the ICX35-HWC Industrial Cellular Gateway and the PLX35-NB2 Network Bridge
