SECTION 9 INSTALLATION 9 7 SERIAL NETWORK INSTALLATION The serial network installation consists of wiring the network and setting each M4000 module on the network with a unique network address Up to 32 M4000 modules can be installed on one network 9 7 1 WIRING THE SERIAL NETWORK Refer to figure 9 5 for a typical schematic of the network and for the pin outs of the network interface connectors When wiring the network the following rules must be followed 1 Wire the network using Belden 9182 single shielded twisted pair cable or an equivalent data communications cable meeting the following spec Wire gauge 22AWG Nom impedance 150 ohms ft Nom attenuation at 1MHZ 0 004 db ft Twisted pair single shielded 2 The total wire length of the network cannot exceed 1000 ft if the network baud rate is set to 344KBPS 2000 ft for 229KBPS and 4000 ft for 106KBPS See section 9 7 2 for details on setting the network baud rate 3 The maximum number of nodes connected to one network is limited to 32 nodes 4 The shield of the cable should be carried through the entire network using the shield tie points on the interface connectors to achieve this The shield tie points on the connectors are not internally tied to anything they are strictly tie points One of these tie points should then be tied to earth ground 5 The two extreme ends of the network should be terminated with 150 ohm resistors as shown in figure 9 5

7. Troubleshooting 1 Verify that only one master is communicating on the network The master is defined as the node which is executing the sfunc13 system functions If two nodes are executing sfunc13s simultaneously a network collision will occur with the corresponding corruption of data 2 Verify that the network wiring is isolated from other high voltage wiring which could induce EMI into the network The network should be routed in a conduit separate from other wiring 3 Replace the slave M4000 module with which the error occurred If the problem persists replace the M4000 module at the master node 7 4 4 ADDRESS OUTSIDE RANGE 0FH This error occurs when an attempt to write to memory outside the data memory range occurs in either the master or slave Verify the corresponding sfunc13 call specifies the proper data range M4010 M4011 M4012 User s Manual SYSTEMS Electronics Group 41 SECTION 7 FAULT DETECTION This Page Intentionally Left Blank M4010 M4011 M4012 User s Manual SYSTEMS Electronics Group 42 SECTION 8 HARDWARE CONFIDENCE TEST The hardware confidence test allows the entire M4000 module hardware to be verified for proper operation The test is resident in all modules and is initiated through SYSdev The hardware confidence test is the same test used at the factory to initially test the production M4000 modules and therefore provides the same 10096 hardware test as provided at the factory The te
8. 2 The master sends 2 words W080 and W082 to the slave at network address 2 storing these two words at W120 and W122 respectively 3 The master then receives 2 words W110 and S112 from the slave and stores these two words in W084 and W086 of the master Note The sfunc13 is a simultaneous system function such that once it is initiated program execution continues without waiting for the sfunc13 to complete Subsequent call of the sfunc 13 will result in a return value of 1 BUSY 2 DONE or an error code 03 10H By examining this return value it can be determined whether the sfunc13 completed and whether it was successful return DONE or failed return error code In this example once sfunc13 is complete it is simply called again Communication occurs continuously and indefinitely until disabled B67 set to 0 block 5 High level 0 if B67 0 enable serial comm 1 2 865 sfunci3 2 2 W80 W120 2 W110 W84 yes communicate with 33 if B65 1 slave 2 4 B66 B65 D if B65 gt 3 error code return value 6 B68 B65 yes save error code in B68 7 8 B065 comm return value B066 comm return value B067 serial comm enable B068 comm error code w080 master send stack W084 master receive stack W110 slave send stack
