TWO VMEbus modules that adhere to the standard can be incompatible with each other Non-GE Fanuc VmE modules that have been designed to the set of standards known as VME64x are generally compatible with PACSystems equipment. However, the following VME64x features are not available 160 pin connectors on the backplane Po/JO connector 3.3 V power supply pins Rear plug-in units(transition modules) Live insertion /hot-swap capability Injector /ejector locking handles EMC(ElectroMagnetic Compatible)front panels ESD(Electrostatic Discharge)features A module with 160-pin connectors can be plugged into 96-pin J1/J2 connectors in a PACSystems main rack or Series 90-70 expansion rack A module that requires +3.3 Vdc power cannot be used in a PAcSystems main rack or series 90-70 expansion rack GFK-2235 Chapter 1 VME Modules for PACSystems 1-3 General requirements for VME Modules A non-GE Fanuc VME Module must meet these general requirements for use with PACSystems equipment The module must meet the same agency approval standards as the PAcSystems equipme The module must comply with the VmE64 specification if it will be located in the main rack The module must at least comply with the VMEbus Specification Revision C 1 if it will be located in a Series 90-70 expansion rack. No earlier version of this specification may be used VMEbus(VME-1)as implemented on the GE Fanuc PACSystems cPl ed The module must be compatible with the characteristics of the industriali Environmental Requirements In selecting a Vme module from another vendor, it is important to pay close attention to the environmental ratings of the module, because individual module ratings can limit the overall system rating. The VMe module should meet the following specifications of PACSystems equipment. For more detailed information on product agency approvals, standards, and general specifications for the system, please refer to the PAC Systems RX7i lnstallation manual, gfK-2223 Specification Requirement Operating Temperature 0 to 60 C (32 to 140 F),(inlet air at bottom of rack Storage Temperature|-40°t85c(-40°to185F) Humidity 5%to 95%(non-condensing) Vibration 1G40-150Hz,0.012npp10-40Hz Shock 15 gs for 11 msec Consideration must be given to maintaining acceptable component temperature when the vme module has other modules on either side of it. the vme module itself should not exceed 22.5 Watts if this specification is to be met 1-4 PACSystems RX7i User's Guide to Integration of vme Modules - June 2003 GFK-2235 Module size requirements Module Height and connectors Single height ( 3U)modules connect to the J1 connector on the rack backplane Traditionally, 3U modules generate or accept up to 24-bit address and 16-bit data transfers. Single height modules are commonly used if space is limited. Because of their size, they are also more resilient to shock and vibration than double height boards. A 3U-size module will require a faceplate adapter to secure the module to the rack rails Double height (6U) modules are electrically compatible with single height modules Most 6U modules can generate or accept up to 32-bit address and 32-bit data transfers Both 3U and 6U modules can be installed in any PAc Systems rX7i main or Series 90-70 expansion rack. However, only the main rack has a j1 and J2 backplane. A J2 backplane can optionally be added to an expansion rack if necessary, as explained in chapter 2 Triple height (9U) boards are not supported by the vmE4 specification and cannot be used in any PACSystems main or expansion rack Module width Both single-Width(0. 8 inch)and double-width(1.6 )inch modules can be installed in any rack in the system. However, modules having more than one board, each with a backplane connector, must be installed in the main rack or in a Vme Integrator expansion rack See chapter 2 for more information about slot spacing, blank slots, and module location restrictions GFK-2235 Chapter 1 VME Modules for PACSystems 1-5 Addressing and Data requirements Modules must have a configurable address range to prevent overlap with gE Fanuc modules'addresses Modules must respond to one or more of the following address modifier(AM) des AM Code Address width Description 29H A16 Non-Privileged data 2DH A16 Supervisory data 39H A24 Non-Privileged data 3AH A24 Non-Privileged Program(main rack only) 3DH A24 Supervisory Data(main rack only) 3EH A24 Supervisory Program(main rack only) 09H A32 Non-Privileged Data(main rack only) OAH A32 Non-Privileged Program(main rack only) ODH Supervisory Data(main rack only OEH A32 Supervisory Program(main rack only) Modules must not respond to GE FanuG-defined AM codes 10H through 1FH Modules that use D16(16 data bits )or D8 (8 data bits )data transfers can be located in the main rack or in an expansion rack. 16 bit data transfers are preferred Modules in an expansion rack must be A24(standard)or A16(short) address compatible Modules that use D32 (32 data bits) data transfers can only be used in the main ra 1-6 PACSystems RX7i User's Guide to Integration of vme Modules - June 2003 GFK-2235
