EtherTRAK®2 and Etherbus®Dual Ethernet I/O Module6.6 High Speed CountersApplicable to: E2-MIX24880, E2-MIX24882, E2-MIX20884, E2-32DI24, E2-16DI24High speed counters can be enabled on the first two to four channels. In the web server or I/O Tool Kitsoftware “Discrete Options” configuration page, check “Enable high speed counters on Channel 1” and/orChannel 2 to enable these modes. This special mode functions in the same manner as the discrete input countfeature for the corresponding input, except that the maximum count rate for the first and/or second input isincreased to 50 kHz (2kHz on the E2/EB-16DI24-D).Note 1: On the E2/EB-MIX-24880-D and E2/EB-32DI24-D modules only, the first high speed counter isconnected to two isolated input screw terminals (43 and 44) and screw terminal 11 is disabled. If the highspeed counting option is not selected, then the pulses are counted from the ordinary discrete input screwterminal in the manner typical of all other input channels. This isolated channel is capable of counting up to50kHz (3,000,000 pulses/min).Note 2: On the E2/EB-16DI24-D module only the first two isolated high-speed counters are capable of countingup to 2kHz (120,000 pulses/min).6.7 Slow/Fast Response for All Discrete InputsIn the web server or I/O Tool Kit software, select “fast response” to use no input filtering. DC input changes asfast as 1 ms will be detected. Selecting the “Slow response” setting will tell the module to look for stable inputsfor approximately 25 ms. This setting will filter contact bounce, which often happens while counting mechanicalswitch closures in noisy environments.6.8 Combination Discrete Inputs/OutputsApplicable to: E2-MIX24880(17-24), E2-MIX24882 (17-24), E2-MIX20884 (13-20)The last eight discrete I/O has both input and output capabilities at the same time. Output functionality for agiven channel may be individually enabled in the “Feature” column of the Discrete Options configurationwindow. For compatibility with I/O drivers that write I/O in fixed blocks, all eight Y (output) registers are alwaysassigned. Only outputs that are enabled may be turned ON. Other output values will be masked in the I/Omodule.All eight channels are always active as inputs. Channels that do not have their output function enabled may beused as inputs. For channels configured as outputs, the input functionality may be used to detect faults in thecorresponding outputs.Important Note: The supply voltage used to power input devices connected to the combination I/O channelsmust match the supply voltage used to power the I/O module to avoid leakage paths or damage to the I/Ocircuitry on these modules. It is recommended that the same power supply be used to power the I/O moduleand input devices connected to these special I/O channels. If a voltage source is applied to the eightcombination I/O channels that exceed the voltage supplied to the rest of the I/O module, unintended powerpaths may result.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
