Simple and secure remote maintenance via the Internet.

Remote maintenance with the Ewon(Eyeswatchingovernet) industrial remote maintenance routers and the Talk2M(TalktoMachine) connection service means secure remote access to machines and systems via the Internet. The system provides a secure IP connection (OpenVPN) that does not place any major demands on IT and only works with outgoing connections, i.e. does not require any open ports or similar for incoming connections. This connection (established on the Talk2M server) can be used to route to the local network and is therefore equivalent to full IP access to the local network in the machine or system. This connection can then be used like a local network connection. USB or serial access (RS232/RS485) and fieldbus connection (e.g. Profibus, Profinet) are also possible via the IP connection.

Cosy = simple IP router, Flexy = IP router with additional functions.

Ewon Cosy is the simple remote maintenance router, i.e. the device establishes the connection via Talk2M(TalktoMachine) and the local network on site. If required, the user can dial in with the eCatcher (OpenVPN client) and thus have an IP connection with his PC to the local network of the machine or system.

Ewon Flexy is also a remote maintenance router, just like Ewon Cosy (see above). However, the Flexy also has interfaces and protocols to communicate locally with connected controllers or devices and to read and write data from there. This allows, for example, alarm management with SMS and e-mail notifications to be set up, data to be logged and sent or cloud services to be operated. Ewon Flexy is also programmable and can therefore be functionally adapted to almost all application requirements.

Talk2M( Talk toMachine) is the connection service for Ewon remote maintenance routers.

Talk2M (TalktoMachine) is the connection service for Ewon remote maintenance routers. Talk2M was specially developed for Ewon remote maintenance routers and is a globally distributed IT structure of servers that are operated exclusively by well-known hosting companies that can guarantee the highest possible availability and the greatest possible security. Talk2M is not a cloud service or similar! No user data is stored via the system! Additional services such as SMS and e-mail relay, M2Web and DataMailbox are integrated into Talk2M. Various APIs (software interfaces) are offered so that external services can be connected to the system.

Free+ is the free basic account with a VPN line for Talk2M (Talk to Machine), Pro is chargeable with parallel lines and user management.

Before an Ewon router can use the Talk2M(TalktoMachine) connection service, the user must create a Talk2M account and register the Ewon router as such in a Talk2M account. To do this, each user first creates a so-called Talk2M account "Free+". It can accommodate any number of Ewon routers and any number of users and has a VPN line (an active VPN connection). This means that if a user is connected to an Ewon router in this account, no second user can connect to another Ewon router in this account. The active connection must first be terminated before another connection can be established. Each Free+ account is free of charge and includes 3 GB VPN data/month. If the data volume has been exceeded 3 times in a row, the account will be capped after the 3rd month after 3 GB (no more remote maintenance can be done in this month).

Every Talk2M "Free+" account can be upgraded to a Talk2M "Pro" account. When upgrading the Free+ to a Pro account, several Free+ accounts can be migrated to the Pro account. A Pro account has 3 VPN lines in the standard package, i.e. up to 3 connections can be active in this account at the same time. Each VPN line has 3 GB of data volume (9 GB in total) per month included. You can theoretically add as many VPN lines as you like to a Pro account. A Pro account is never capped. If the data volume is exhausted, connections can still be made, but the additional data volume required is then subject to a charge.

Unlike the Free+ account, the Pro account has real user management, i.e. you can create user groups and device pools and then assign the user groups to the device pools and vice versa. The rights of users and groups can be administered. The visibility of specific Ewon routers can also be determined for certain users and user groups. This makes it possible to map almost any organizational form in the Pro account and thus adapt it to the individual needs of the users. There are often many users and hundreds or even thousands of routers in a Pro account.

M2Web(MachinetoWeb) is an access to Talk2M( Talk toMachine) without a VPN connection, only with a browser.

M2Web(MachinetoWeb) is a web-based access to Talk2M(TalktoMachine) that only requires a browser, not a VPN client. All web-based services of the remote maintenance routers themselves, but also of the connected devices, can be used via M2Web. For example, M2Web can be used to configure the Ewon routers themselves without first creating a VPN connection with a VPN client (eCatcher). M2Web can, for example, also enable the end customer to call up the websites of the end devices and view the machine's production data and much more.

The DataMailbox is a temporary data storage in Talk2M to temporarily store tag values.

Ewon Flexy has interfaces and protocols to communicate locally with connected controllers or devices and to read and write data from there. The data is then stored in separate variables, so-called tags, on the Flexy. The values of the tags can then be further processed in the Flexy in alarm management, data logging, etc.

Several services are integrated in Talk2M (Talk to Machine), the connection service for Ewon remote maintenance routers, including the option of temporarily storing data from the routers (tag values) in the so-called DataMailbox (similar to the mailbox on cell phones).

The user can then use the DM-API(DataMailboxsoftware interface) to retrieve the data from the DataMailbox into his application. As a remote maintenance router, Ewon Flexy can therefore also serve as a database for predictive maintenance or other cloud-based data services.
