page 2 oper ation pci bus interface the pci bus is a high speed alternative to i sa bus, it has been designed to o ver come some of the limitations of i sa bus, and pro vide faster throughput for i/o intensive peripher al devices. pci bus also supports plug and play configur ation which allo ws the system softwar e to allocate r esour ces during initialisation helping to o ver come r esour ce conflicts, which might exist in a system. the apci-r e l a y8/i n8 uses a single chip pci bus slave controller which is designed and manufactur ed b y pl x t echnology. this device has been designed to fully support the pci 2.1 specification and pro vides plug and play softwar e capabilities. during po wer-up initialisation the pci b ios will detect the car d and assign a unique i/o addr ess location and interrupt line. this ensur es that ther e ar e no r esour ce conflicts on the pci bus. multiple car ds ar e supported through this mechanism without the need for addr ess decode links. the pl x device contains a standar d type 00h configur ation space header. the table belo w sho ws the r egisters within this header which ar e r equir ed for configur ation of the apci-r e l a y8/i n8. configur ation s pace header these r egisters can be accessed using pci b ios functions. please contact ar com control systems customer support team (t el: 01223 412428) for a copy of the pci b ios specification if r equir ed. 2192-09101-000-000 j594 apci-relay8/in8 offset 00-01h 02-03h 18-1b h 2c-2dh 2e-2f h 3ch register name v endor i d device i d base addr ess r egister subsystem v endor i d subsystem i d interrupt line description i d of pci device manufactur er i d of pci device i/o base addr ess assigned to car d i d of boar d manufactur er i d of boar d interrupt line assigned to device value 10b5h (pl x t echnology) 9050h 0000xxxxh 13ab h (a r c o m) 0594h(apci-r e l a y8/i n8) 0xh

i/o map the apci-r e l a y8/i n8 uses two consecutive i/o addr ess locations to access the onboar d functions. the i/o base addr ess is set b y the pci b ios during initialisation (r efer to the pci b u s section of this manual for details). a pci b ios function call may be used to determine the base addr ess once the system has been initialised. multiple boar ds may be used in a system as each will be given a unique i/o addr ess. page 4 2192-09101-000-000 j594 apci-relay8/in8 offset 00 00 01 01 register name r elay output r elay s tatus r elay enable opto inputs read/write w rite r ead w rite r ead comments configur e r elay outputs r eadback s tatus enable r elay latches r ead opto inputs bit function bit 0-7 for r elay 0-7 ?0? = r elay nc contacts closed ?1? = r elay no contacts closed bit 0-7 for r elay 0-7 ?0? = r elay nc position ?1? = r elay no position bit 0 ?0? = all r elays of f (nc position) ?1? = r elays enabled. bit 1-7 unused. bit 0-7 ?0?=input on ?1?=input of f
