MCOMS505 program is as follows The 505 program reads the data that is to be transmitted from the TI 505 processor and stores this in an internal buffer of the S3016 505 The data that was read from the slave node on the previous network communication is then written to the TI 505 processor This is performed in a sequential fashion for all nodes 2 thru 32 that are enabled for communications The data that is passed for each node is defined in section 3 4 Note No data task code communication occurs for any nodes that are disabled Once the data for all the enabled nodes is updated the communications status stack is then written to the TI 505 processor see section 3 3 6 for details on this data Once this is done the process is then started over with the data for the first node being transferred to and from the TI 505 etc This communication between the TI 505 and S3016 505 is performed continuously Asynchronously to the TI 505 to 3016 505 communications the communications to the slave nodes over the network is performed The data for the first enabled node is transmitted to the slave node and the data that is to be read is read from the slave This data is saved in an internal buffer of the S3016 505 Communications to the next enabled node is then performed and so on for all enabled nodes This is repeated continuously for all enabled nodes Note Communications for any disabled nodes is not attempted This communica

22. 3016 505 User s Manual 6 The network should be wired directly to the network comm port connectors No intermediate terminations or splices should be used The network should be wired in direct connect topology as shown not in multi drop or cluster topologies Note The network comm interface connectors contain two sets of and terminals The two sets of terminals are tied together internally on the board to to and are provided as tie points to ease wiring Communications across the network will continue even if one of the nodes has failed provided all the connectors are installed in their respective board However if a connector is pulled from it s board communications to the boards downstream will be lost the internal tie point will be broken If it is desired this situation can be avoided by wiring the connectors as shown in figure 2 2 2 2 SETTING THE NETWORK ADDRESSES IN THE 3000 M4000 NODES When using the MCOMS05 program the network address of the S3016 505 is automatically set to address 1 For this reason the S3016 505 network address does not have to be set by the user Each of the slave S3000 M4000 nodes on the network must however be set by the user with a unique network address between 2 and 32 This is how the S3016 505 can distinguish one node from another To set the network address of a particular S3000 M4000 node perform the following 1 Connect the IBM PC or compatible running SYSdev from the
