    Hi Nick,

    I'm assuming you're using JCo 2.x (and not 3.x where by default all connections are stateless). If you're using a connection pool, the connections should get reset when you return the connection to the pool via JCO.PoolManager.releaseClient(JCO.Client); otherwise you might need to call JCO.Client.reset() yourself.

    Another possibility for odd results could be re-cycling of JCO.Function objects. It's usually best to create them fresh for each call, otherwise you'd have to ensure that the interface parameters are initialized properly.

    Cheers, harald
