Information exchanged between RIO drop and RIO head includes register data I O module identification and bus status 4 2 RIO DROP REGISTERS The RIO drop Class 8030 Type CRM931 has a total of 128 on board data registers 64 input and 64 output that can be rack addressed to individual slots of the drop If this limit is exceeded Modsoft will flag a mapping error while programming At run time the SY MAX CRM931 will flag an error if the module code for any register in an I O module changes after initialization of the module 4 3 REMOTE l O BEHAVIOR When the system is operating normally communication between the RIO head and its associated RIO drops occurs only when the CPU scans the program When scanning is halted outputs controlled by the RIO drop are either frozen or placed in a pre determined state Chapter 4 Operation Page 14 30598 822 01A1 4 4 RACK ADDRESSING The CRM931 module is compatible with both SY MAX Register RIM ROM Modules and SY MAX Digital HIM HOM Modules and can coexist on an S908 remote network with other CRM931 modules and S908 drops The SY MAX CRM931 module converts all supported SY MAX module IDs to their corresponding Modicon Module IDs Modicon Module IDs have an associated set number of input and output registers mapped to them A CRM931 module has one ID when located in slot 1 of a register rack and one of four IDs when located in slot 1 of a digital rack The digital rack ID allow
6. Mid oy 4 5 2 SY MAX Digital I O Modules SY MAX Digital I O modules are mapped to the CRM931 module in register slot 1 of the remote rack Since the number and combination of installed digital I O modules can greatly vary a digital rack has a set number of input and output registers assigned to it This number is determined by the number of slots in the rack For example the HRK200 rack uses the maximum possible value of eight input and eight output registers Empty registers have a zero value and no effect The CRM931 module has a different ID code for a digital rack than for a register rack Therefore the registers may be assigned to slot 1 The SY MAX digital I O points are assigned to Modicon I O discrete points according to slot location in the standard SY MAX rack addressing manner The following example illustrates I O mapping Discrete output modules have their sensed value read back in their corresponding input registers Table 10 Mapping for SY MAX I O Modules in a Digital Rack Register Register i Example Slot Number Register Module Type Addressing Module CRM931 DG8 Discrete 128 point input 128 point output 000001 000128 potential potential 100001 100128 Table 11 Mapping for SY MAX Digital I O Modules Digital Slot Number Digital Module Type Discrete Addressing 1 8 point input 100001 100008 000009 000016 S S point output 100009 100016 3 empty m 4 E 8 po
7. With respect to speed RIO has several advantages over other proprietary PLC communication methods RIO data transfer speed is predictable because of HDLC protocol implementation Message collisions do not occur because only one node transmits at a given time Each drop has high data integrity due to the frame check sequence and error checking at the physical protocol layer The RIO network supports communications between a PLC and one or more drops of I O modules that are dispersed throughout a local area e g a manufacturing or processing facility The RIO head or processor a master node initiates all messages on the RIO network All other nodes on the network communicate with the RIO head via RIO adapter modules located at the drops The CRM931 RIO adapter module is compatible with a Modicon Quantum or E984 785 Programmable Logic Controller PLC when inserted in a remote SY MAX Class 8030 Type HRK or Type RRK rack The remote rack must be part of a Modicon 908 RIO system Modicon Modsoft Software Revision 2 31 or later is required to use the CRM931 RIO adapter module Contact a Square D distributor for upgrade information Chapter 1 Overview Page 2 30598 822 01A1 1 2 RIO DROP MODULE FEATURES Figure 1 on page 3 shows the CRM931 RIO adapter module The module offers the following features User selectable rotary switches identify the RIO drop module as one of up to 31 drops per RIO head See Table 4 o

24. see Table 4 If proper rack addressing does not occur the processor and RIO head will not look for the RIO adapter and communication will never occur Illumination of the COMM ACTIVE LED confirms successful communication initialization When the hardware is installed and configured properly the most common problem associated with an RIO adapter module which is properly communicating with its RIO head but not controlling its associated I O lies in the rack addressing of the drop Note For register racks no registers should be assigned to the RIO drop itself slot 1 but should instead be assigned to the remote slots in which the other modules reside See examples in Chapter 4 of the RIO head instruction bulletin For digital racks all digital registers are assigned to the CRM931 slot 1 Chapter 5 Troubleshooting Page 20 30598 822 01A1 A WARNING UNINTENTIONAL EQUIPMENT OPERATION Be sure switch settings for the drop correspond with the correct drop number Improperly set switches can cause equipment to act in an unpredictable manner An improperly coded drop number when not a rack addressed drop will be ignored when addressing is identical for two or more drops may create a situation in which either two drops conflict or one drop responds while the other does not The RIO head may not detect identical drops for all situations Failure to observe this precaution can result in death serious injury or
