5.3.3 When Connected to a FP Series PLCError codes which are sent from the PLC are listed in the table below. For details, refer to the table ofMEWTOCOL-COM communication errors in PLC user’s manuals.For GT01, GT11 and GT21Code No. Content Cause and solutionER21Data errorA data erroroccurred duringcommunication.1) There is an error in the communication condition settings. Checkthe PLC and GT baud rate and transfer format.2) There is a temporary error due to noise, etc. Re-supply power tothe PLC and GT.ER22Overrun errorThe PLC isn’treceiving data.The CPU unit’s reception buffer is overflowing.There could be an error in the PLC.Re-supply power to the PLC and GT.ER40BCC errorA data erroroccurred duringcommunication.1) There is a temporary error due to noise, etc.Re-supply power to the PLC and GT.2) There is an error in the CPU unit. Re-supply power to the PLCand GT.ER41Format errorThe PLC has beensent a commandthat doesn’t matchthe protocol.1) There is a temporary error due to noise, etc.Re-supply power to the PLC and GT.2) There is an error in the CPU unit. Re-supply power to the PLCand GT.ER42NOT support errorThe GT has sent anon-supportedcommand to thePLC.1) There is a temporary error due to noise, etc.Re-supply power to the PLC and GT.2) There is an error in the CPU unit. Re-supply power to the PLCand GT.ER53BUSY errorThe PLC iscurrentlyprocessing anothercommand.A large amount of data is being communicated with anotherRS232C port on the PLC.Wait until the error is gone.ER60 Parameter errror The specified parameter does not exist, or it cannot be used.ER61Data run errorThere is an error inthe register orrelay number.A register or relay number which doesn’t exist in the PLC wasspecified during screen creation using GTWIN.Correct the output device being used with the part, or the transferof clock data to an external device.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: info@ctiautomation.net
