Encore Engage Gateway 17Part 1615959−01 2019 Nordson CorporationIO Module 8The assignment to each gun is sequential, that is to say, the first byte of IOModule 8 is assigned to gun #1, the second byte is assigned to gun #2, andso on. The value in these bytes is a new preset number which is to be usedby a given gun, and is sent to that gun’s KV and Flow node−pair via theData Table 14 command (using multicast addressing). When the gateway isinitialized, it will fill this space with zeros indicating to the gateway there isno change to the current preset (all nodes, by default, start up using preset#1). Since all gun control nodes always power up using Preset 01, it isrecommended that the PLC programmer initialize all of IO Module 8 tocontain “1” for every gun number. The PLC program may change a gun to anew preset by simply writing to that gun’s byte in IO Module 8. When thegateway detects a change has occurred in any of the bytes in this IOModule, it sends a multicast message out to the node−pair associated withthat byte (gun). Therefore, as the Gateway polls its way through IOModule 8 looking for changes, it is possible for it to send out 32 multicastmessages; one for each byte change detected.IO Module 9This IO Module contains 2 bytes. The first byte defines which informationdata the Gateway should present to the PLC as defined in Table 4. Thesecond byte defines the page number for the 16 guns for which theinformation data is contained in IO Module 28. The value of 0 is forGuns 1−16; value of 1 is for Guns 17−32.All of the IO Modules are discussed in more detail in later sections. |
