A single account user cannot maintain two eCatcher connections at the same time. To keep both engineering laptops connected to the Ewon Cosy, assign a different account user to each laptop and confirm that the account permits at least two concurrent connections.
Identify the Connection Constraint
The limiting factors are the user session and the account's concurrent-connection allowance. Reusing one user on the second laptop requires ending that user's active eCatcher session on the first laptop. Remote Desktop access to another computer does not, based on the available evidence, share or transfer the first computer's eCatcher tunnel.
Check the eCatcher Account Limit
| Account level | Concurrent connections | Two-laptop result |
|---|---|---|
| Free | 1 | Cannot connect both laptops concurrently |
| Light | 2 | Supports two concurrent connections |
| Pro | 5 | Supports two concurrent connections |
Review the limit under the Account tab in eCatcher. A Pro account may permit additional concurrent users when extra capacity was purchased or included in a custom contract.
Configure the Two-Laptop Connection
- Create a second user in the same eCatcher account.
- Assign one account user to the controls laptop and the second user to the HMI laptop.
- Verify under the Account tab that the subscription allows at least two concurrent connections.
- Connect each laptop through eCatcher using its assigned user.
- Confirm that the first laptop can reach the PLC while the second laptop can reach the HMI without either eCatcher session disconnecting.
The account can contain an unlimited number of users, but creating users does not increase the concurrent-connection limit. If the account permits only one connection, upgrade or add concurrent capacity before attempting simultaneous access.
FAQ
Can two computers connect to one Ewon Cosy at the same time?
Yes, if each computer uses a different account user and the eCatcher account allows at least two concurrent connections.
Why does eCatcher log out when I connect from the second laptop?
A single user can maintain only one connection at a time. Create a second account user instead of reusing the same credentials.
How many concurrent eCatcher connections does each account allow?
The stated limits are 1 for Free, 2 for Light, and 5 for Pro. Check the Account tab because purchased capacity or a custom Pro contract can change the applicable limit.
