Hi @jessedcpc, you have to add the next parameters to your device configuration:

"connectAttemptTimeMs": 5000,
"connectAttemptCount": 5,
"waitAfterFailedAttemptsMs": 300000,
"retries": true,
"retryOnEmpty": true,
"retryOnInvalid": true,

Also, it is recommended to update your Gateway to the newest version (3.1) via the master branch or other suitable for you way. Modbus Connector was remastered and fixed a lot of bugs in the new version.
