C80prox – Marklin Digital Control Program for PC’s Advanced Topics Registers C80prox contains 60 arithmetic registers set up as 20 groups, (0 to 19). Each group of registers contain a 'a' and 'b'. Only 1 register pair can be active at a time. This register pair is pointed to by the register pointer. Both registers can be loaded with data, incremented, decremented and tested using the flags as previously described. a {r} = {v} b {r} = {v} These 2 commands will stored the required data {v} into the register {r}. Each command does not affect the other register in the group. The register pointer is changed to register pair {r}, and these registers become the currently active group. a {r} + {v} b {r} + {v} a {r} - {v} b {r} - {v} These commands will increment {+} or decrement {-} register {r} by a value {v}. Each command does not affect the other register in the group. The register pointer is changed to register group {r} and these registers become the currently select active group. The register number {r} must be specified, but if {v} is not, 1 is assumed. r = {r} This command will change the register pointer to {r}. Register pairs {r} will then become the currently active pair. Note: Flags 17 and 18, as discussed above, will always reflect the currently active register pair. The range of values that can be stored in registers is from 0 to 999. Flags C80prox has 100 semaphore flags (20 system, 80 user). These flags are either set '1' or not set '0'. C80prox contains specific instructions on setting, resetting, toggling and testing these flags. i.e.: Command Example Meaning s f 67 set flag 67 (make flag 67 a '1') r f 89 reset flag 67 (make flag 89 a '0') t f 76 toggle current status of flag 76 c 32 f 34 copy flag 32 to flag 34 t 99 g 12 test flag 99 and if set goto label 12 in the current sequence t 99 s 13 test flag 99 and if set gosub to label 13 in the current sequence n 99 g 12 test flag 99 and if NOT set goto label 12 in the current sequence n 99 s 13 test flag 99 and if NOT set gosub to label 13 in the current sequence fs display the current setting of all flags Page 30 Version 1.1 October 16, 2003
C80prox – Marklin Digital Control Program for PC’s System Flags Contained within these 100 flags, the first twenty, 0 to 19, should not be used for setting, resetting, toggling or being copied to. They can however be copied and tested, using the 'cf' and 'tg' commands. Flag Meaning 0 Set if error condition was detected on the last S88 read 1 – 16 Result of Last S88 read. If Flag 0 set, then these settings maybe in error. 17 Set if the currently active a & b register set are NOT equal 18 Set if the currently active a register is NOT zero 19 Set if the last clear S88 module command detected that at least 1 contact is still active Indirect Flag A special indirect flag 100 is used to indirectly access any of the other flags (0 to 99). The contents of the currently active 'a' register is used as the actual flag number. ie: if the currently active 'a' register contains the value 42, then the following commands are equivalent: s f 100 s f 42 Multiple Heading of Locomotives C80prox allows the definition of up to 200 locomotive consists. Each logical locomotive number (1 to 200) can be assigned up to 4 different physical digital addresses. When controlling this logical locomotive, all associated digital addresses will be addressed and classified into one unit. For example: Logical Locomotive #137 has the three physical digital addresses, 17, 18 and 19 set. Locomotive Number Addr1 Addr2 Addr3 Addr4 137 17 18 19 Locomotive 137 has been set up as a triple header consist. Digital addresses 17, 18 and 19 have been linked together. When C80prox controls locomotive #137, then the physical locomotives 17, 18 and 19, will act accordingly. Other logical locomotives can still be defined using the address 17, 18 or 19, either as single, double or quad heading consists. Individual digital addresses may be defined in any number of logical locomotives. You set up single/double/triple or quad header locomotives by using the c80prox set up program ‘SetPro’. Redefinition’s can be made from within C80prox or sequence. There are 8 commands to define or redefine multiple header locomotives. m {l} a {a} i m {l} b {a} i Page 31 Version 1.1 October 16, 2003
