Bus Slave Modules Slave VME modules often have a shared RAM interface through which the VME module data is exchanged with the VMEbus master Flow of data between the slave module and the VMEbus is controlled by the bus master module Certain slave modules may have interrupt capability which if used must be done with care and in such a way as not to interfere with the Series 90 70 PLC system for details refer to Interrupts on page 3 5 Currently VME modules may interrupt only each other not Series 90 70 modules Series 90 70 PLC I O modules or the Series 90 70 CPU VME modules transfer data in three widths 8 bits 16 bits and 32 bits Some modules support all three some only two typically 8 and 16 bits and some only one The Series 90 70 PLC supports data widths of 8 bits and 16 bits It does not support a data width of 32 bits Typically only modules which transfer data in 8 bit or 16 bit widths are compatible with the Series 90 70 PLC VME module support up to three address widths 16 bits 24 bits and 32 bits These are referred to respectively as Short 16 bits Standard 24 bits and Extended 32 bits The Series 90 70 PLC supports address widths of 16 bits and 24 bits It does not support 32 bit address widths If your module requires a 32 bit address you may still be able to use it by either wiring the 25th through 32nd address bits or by installing a J2 backplane and driving the 25th through 32nd address lines external to the

31. The explanation for the difference is that these jumpers may be set differently depending on the types of memory devices used on the module The application was done with J3 IN but this may work better with J3 OUT J3 0UT restricts the module to responding to address modifier 2DH instead of 2DH and 29H Programming All of the serial operating parameters such as baud rate parity stop bits and others are programmable on a port by port basis As noted above the power up default parameters were used for this demonstration the entire power up default list is on page 4 25 of the Xycom manual There are 2 basic modes of operation character read write and record read write Character read write basically turns the board into a four port USART and requires that the Series 90 70 CPU handle each characterindividually This would have severely limited the baud rate which could be handled without missing characters coming into the port and would have required the construction of a PLC based buffer handler for the data The record read write mode was used since this takes advantage of the internal buffers on the module This application closely followed the example in the Xycom manual on page 3 12 to 3 14 reading a record under polled operation With reference to this example the host base address is 0 the base address of the I O interface block is 2800H the command block is at 2A00H the data buffer is at 2A14H and the command is set t
