Document No. EX##-TDO0011 September 7, 2010 Product Development Div.5, SMC Corporation Dear users of the serial transmission unit, EX12#-SDN1, Please be informed of the handling precautions of the setup file, EDS. Usage of the new EDS file (ex12#-sdn1_22_v14.eds) 1. This new EDS file is to be used for the SI unit (EX12#-SDN1) of the device revision 2.008 with the identification mark G on the label. 2. If the new EDS file is used for older SI units than the device revision 2.008, some configuration software of some manufacturers may give a warning message as they do not have the parameter functions. In this case, use the old EDS file. Some configuration software may not be able to distinguish the new EDS file from the old EDS file. Usage of the old EDS file (ex120A.eds) 1. The old EDS file is to be used for the SI unit (EX12#-SDN1) of the device revision 2.007 which does not have the identification mark G on the label. 2. If this old EDS file is to be used for the SI unit of the device revision 2.008 with the identification mark G on the label, the newly added parameter functions can not be set. The following two are the newly added parameter functions. -"Hold/Clear" : Output operation setting when I/O connection is time-out. (MOD/NET blinks in red) -"H/C (Delete)" : Output operation setting when I/O connection is deleted. (MOD/NET blinks in green) There will be no problem in using the old EDS file when these functions are not used.
