NORITAKE ITRON

Command	I/O Counter

Description	The 31 I/O counters use pre-define variables which can be reset and tested for value. The counter uses an unsigned 32bit register (U32) with names CNTKxx where xx=00 to 30. They require the I/O to be set as an interrupt but do not require an associated INT() command. Counter increment depends on the rising or falling edge of the interrupt. The command RESET(CNTK00) resets to zero the I/O counter on K00. The maximum counter speed is 0-10kHz+ and is dependent on other interrupt and entity usage.

Syntax/Parameters	CNTK00-CNTK30

Example	IF(CNTK00>300?Func300); //if greater than 300 run function called Func300 TEXT(K00Text,CNTK00);; //update counter value on page and refresh screen

Command	RunTime Counter

Description	The RUNTIME counter uses pre-define variables which can be set and tested for values The command Reset(RUNTIME) sets all vales to zero and starts the timer. This runtime counter is independent of the real time clock and runs continually so no setup is required.

Syntax/Parameters	CNTMILLI - Increments every millisecond 0-999 CNTSECS - Increments every second 0-59 CNTMINS - Increments every minute 0-59 CNTHOURS - Increments every hour 0-23 CNTDAYS - Increments every 24 hours CNTRUN - Increments every millisecond since system reset. 86,400,000 = 1 day - v47.12.

Options	RunTime Counter Interrupts Wrap-around interrupt for the RunTime counter have been added. INT(name,CNTMILLI,function); // function called every 1000ms INT(name,CNTSECS,function); // function called every 60s INT(name,CNTMINS,function); // function called every 60mins INT(name,CNTHOURS,function); // function called every 24hours INT(name,CNTDAYS,function); // function called every 2^32days For timer resolutions of less than a second, use TIMER0 to TIMER9.

Example	IF(CNTMINS>30?FuncHalfHour); //if greater than 30 minutes run function called FuncHalfHour TEXT(MinsText,CNTMINS);; //update counter value on page and refresh screen
