Counters when a channel is being configured for PTO or PTO w Ramp if the Counter Disabled parameter is visible in the programming software it has no effect Counter Disabled is only used for channels configured as Type A or B High speed Counter Communication Timing at 4800 Baud and Lower For all Nano and Micro PLC CPUs care must be taken setting timeouts and message lengths when operating at 4800 baud or lower Messages at this rate are longer in duration and may cause various timeouts within a system This can become worse on the Micro 64 CPU because the scan times on this unit are typically slightly longer Monitoring Using Proficy Machine Edition When opening multiple monitoring windows in PME or VersaPro while connected to a CPU one of the following error messages may be observed 0x010D Lost communication with COM server or Monitoring Error Too many windows open If this happens close the error window exit the PME application and then reopen PME to resume monitoring Disconnecting and reconnecting Machine Edition may solve the problem High Speed Counter Signal Frequency For all Nano and Micro PLC types that support High speed Counters the timebase GFK 2566A register does not provide consistent results when the HSC is used to measure signals of continuously varying frequency the data values are not consistent This does not happen while measuring a signal with constant frequency Shorting Signals on Port 2 Ca

Modbus RTU communication PTO at 65KHz 3 HSC channels configured as counters and 4 expansion modules connected sometimes the Micro does not respond to one of the Modbus commands Under such full load conditions Micro s UART occasionally fails to process one byte information which is the cause of the problem This issue is not observed with 175K baud rate To correct this problem have the Client PLC resend the command when the error 0x0B91 is received Watchdog times out when SNPX write command is triggered after Update real time datagram command Whenever a SNPX write command is fired after update real time datagram command the watchdog times out for the few combinations of SNP timer values Example T1 100 T2 0 Disabled T3 0 Disabled T4 2000 T5 0 Disabled Winloader is able to update the firmware with OEM locked When OEM key is enabled updating the firmware should be possible only by entering the OEM key password Currently even when the OEM key is enabled firmware update is possible without password prompt GFK 2566A Uploading the logic with real data results in losing the precision of the real constant values When user logic containing the REAL data values is uploaded its precision is lost in PME and hence Equality of the logic is lost This is because PME represents the value of real number in scientific notation with precision of 6 digits after decimal point For example if a value of 2147483648
