Focas Constants and Variables
Focas Source Variables
Focas variables are used to hold data retrieved from Focas enabled devices.
The information in the curly brackets are parameters that must be filled out to specify additional detail about the data being acquired.
Some variables optionally support multiple paths. Valid options are nothing, a path number, or All. These are denoted in the variable list with a {} inside the variable brackets: [focas.variable_name{}]. The following are example values to determine which path to read:
- Path 1:
[Focas.cycle_status]or[Focas.cycle_status{1}] - Path 2:
[Focas.cycle_status{2}] - Loop (checks if a variable is true for any path):
[Focas.feed_hold_status{All}]

| Current Executing Block RLN [Focas.current_block_rln{}] | The variable will hold the contents of the current line being executed until reaching the 1st new line or 500 characters, whichever comes first. This variable will also remove line numbers that begin with the letter 'N' as well as remove any comment at the end of the line. Any individual path. |

By default the comment must be (PARTNUMBER=123456-01) where 123456-01 is the actual part number. (PARTNUMBER=); will return NONE. If your Focas part syntax is not "PARTNUMBER=" place the correct syntax in place of PART_NUMBER_IDENTIFIER. The syntax parameter is case sensitive. This parameter is optional, if your part syntax is "PARTNUMBER=" then the portion including {} can be omitted. Spaces and parentheses in the comment are ignored. Use this to find a part number in comments when your program does not start immediately after being loaded. Any individual path. Works with CNC Memory and Fanuc Data Server. Cannot read from External Memory. |
| Part Number Executing Program [Focas.part_number_fep{}]{PART_NUMBER_IDENTIFIER} | Returns the part number from a comment in the executing program regardless of where the machine is in the program. Part Number Identifier syntax works the same as [Focas.part_number]. Use this to find a part number in your executing program comments when your program starts immediately after being loaded. Any individual path. Works with CNC Memory and Fanuc Data Server. Cannot read from External Memory. |
| Part Number Main Program [Focas.part_number_fmp{}]{PART_NUMBER_IDENTIFIER} | Returns the part number from a comment in the main program regardless of where the machine is in the program. This variable will always read from the main program even if the machine is currently in a subprogram. Part Number Identifier syntax works the same as [Focas.part_number]. Use this to find a part number in your main program comments when your program starts immediately after being loaded. Any individual path. Works with CNC Memory and Fanuc Data Server. Cannot read from External Memory. |
| Program Comment [Focas.comments{}]{string} | Searches the Main Program for the comment after the provided search string. If no string is provided all comments in the main program are returned. Any individual path. Works with CNC Memory and Fanuc Data Server. Cannot read from External Memory. |

Please note that when using PMC address as a result within an expression you must use parenthesis for example:[PCSDB.send_part_start] {([Focas.pmc_address_value]{D52,D54})}. Any individual path. |
| Reads a Bit Value of an Address [Focas.pmc_address_bit_value{}] {PMC ADDRESS,BIT (0-7)} | Returns a 1 or a 0 for the specified bit. Any individual path. |
