Using the Data Highway Plus Network 2 5 Application Guidelines Consider the following application guidelines when configuring a DH link for your system e Minimize the number of DH nodes to achieve acceptable response times Keep in mind the size and frequency of messages exchanged between devices e Limit the number of stations on your network when you are trying to achieve the fastest control response time Establish separate DH networks to bring on additional stations e Do not add or remove stations from the network during machine or process operation If the network token resides with a device that is removed the token may be lost to the rest of the network The network is automatically reestablished but it could take several seconds Control would be unreliable or interrupted during this time e When possible do not program controllers online during machine or process operation This could result in long bursts of DH activity increasing response time e When possible add a separate DH link for programming processors to keep effects of the programming terminal from the process DH link Publication 1756 UM514B EN P February 2003 2 6 Using the Data Highway Plus Network Two Methods of Communication Over DH Using DH Messaging Publication 1756 UM514B EN P February 2003 The 1756 DHRIO module acts as a bridge for two methods of communication These methods are e DH Messaging e Control and Inform
