Corporate IT documentation

Before installation, agree on the connection method, separation of the machine network and rules for service access. You can give this brief overview to the network administrator.

The principle of connection via Ewon and Talk2MThe computer and the Ewon router establish an outgoing connection to the Talk2M cloud. The PLCs and HMIs are on the machine network behind the router.Technician’s PCeCatcherTalk2MVPN cloudEwon routerWAN / LANPLC / HMIMachine networkOutgoing connectionsOutgoing connectionsSimplified diagram. Network and security conditions are approved by the IT administrator.
AreaWhat to prepare and check
Internet connectionBoth the router and the computer establish an outward connection to Talk2M. For standard access via Talk2M, it is not necessary to configure inbound port forwarding to the production network.
Firewall and proxyFor Talk2M, allow the necessary outbound communication in accordance with the current HMS list. The basis is TCP 443; HMS also recommends UDP 1194. The range of domains and any exceptions must be approved by the IT administrator.
DNS, time and certificatesEnsure that device names are translated correctly and that the device time is accurate. If the network performs TLS/SSL inspection, check its impact on Talk2M certificate verification. Limit any exception to the necessary communication.
Users and permissionsUse personal accounts, multi-factor authentication and access only the devices you need. Advanced organisation using Pools and Groups requires a suitable Talk2M tariff.
Approval and operationDesignate an account administrator, set out rules for external servicing, define the scope of permitted intervention, establish record-keeping procedures and outline the process for revoking access. Before handover, verify the connection and permission restrictions.
Please check with HMS for the current server addresses. The list is subject to change. We therefore do not include specific IP addresses in this overview. The requirements relate to Talk2M; Ewon Edge & Cloud has its own documentation.

Safe connection and remote service guidelines

Address security throughout the entire setup: from Talk2M accounts via the router to the separation of production and corporate networks. Our article provides examples using Ewon routers and W&T firewalls, and also covers permissions and corporate procedures.

Secure remote access: Ewon, Talk2M and W&T firewalls

The specific proposal is based on operational requirements and a risk assessment. Installing the router alone does not ensure that the organisation’s obligations are met.
