[. . . ] Z904-E1-04 DeviceNet Safety DST1-series Safety I/O Terminals OPERATION MANUAL DST1-series Safety I/O Terminals Operation Manual Revised March 2008 iv Notice: OMRON products are manufactured for use according to proper procedures by a qualified operator and only for the purposes described in this manual. The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. !DANGER !WARNING Indicates an imminently hazardous situation which, if not avoided, is likely to result in serious injury or may result in death. [. . . ] Goes into RUN Mode when safety I/O communications are started. Selecting this mode and executing the following operations causes startup in RUN Mode from that point onwards. · Locking the configuration · Turning OFF the power after changing to RUN Mode Safety I/O communications are not possible in this mode. 1972/01/01 After Establishing Safety I/O Connection --- Threshold Run Hours 0 to 429, 496, 729 hours --S Last Maintenance date Execution Mode (DST1XD0808SL-1 only) 1972/01/01 to 2038/01/19 After Establishing Safety I/O Connection Auto Execution IMPORTANT If the power is turned OFF in Idle Mode, the next operation will not start in RUN Mode even if Auto Execution is set as the execution mode and the configuration is locked. The power must be turned OFF in RUN Mode. IMPORTANT Safety I/O communications cannot be used when Auto Execution is set as the execution mode. To use safety I/O communications, set After Establishing Safety I/O Connection as the execution mode. 31 Editing Device Parameters Section 3-1 3-1-3 S Safety Input Parameters Value 0 to 126 ms (in increments of 6 ms) 0 to 126 ms (in increments of 6 ms) Not Used Test Pulse from Test Output Description Sets the OFF/ON delay time. Default 0 ms Parameter name Off On Delay S Off On Delay Sets the ON/OFF delay time. 0 ms S Safety Input Channel Mode The safety input is not used. (External input device not connected. ) Specifies connecting a device with a contact output in combination with a test output. When this mode is selected, select the test output to use for the test source and then set the test output mode to Pulse Test Output. When these settings are made, contact between the input signal line and the power supply (plus) and short circuits with other input signal lines can be detected. Specifies connecting a safety device with a semiconductor output, such as a light curtain. Not Used Used as Safety Input Used as Standard Input Safety Input Test Source Not used Test Output 0 Test Output 1 Test Output 2 Test Output 3 S Dual Channel Safety Input Mode Single Channel S Specifies connecting a standard device (i. e. , a non-safety device). If the channel mode of a safety input is set to Test Not Used Pulse from Test Out, the test output is selected for use in combination with the safety input. Set the channel mode of the test output selected here to Pulse Test Output. If Single Dual Channel Channel is selected, the safety input that would be Equivalent paired for the dual channel parameter will also be set to Single Channel Mode. Specifies using the Dual Channel Equivalent Mode with a paired safety input. Specifies using Dual Channel Complementary Mode with a paired safety input. Sets the time to monitor the logic discrepancy in the dual channel input logic. Input logic, however, will not be evaluated when this value is set to 0 ms. S Dual Channel Safety Input Discrepancy Time Dual Channel Equivalent Dual Channel Complementary 0 to 65, 530 ms (in increments of 10 ms) 32 characters max. 0 ms --- I/O Comment Sets an I/O comment for the safety input. None The I/O comment set here is used as the I/O tag in the NE1A-series Logic Editor. Sets the operating mode for the maintenance counter. Sets the threshold value for the maintenance counter. [. . . ] The setting can be read for a specified number of points. Write Sets either hold or 10 hex clear as the output status after a communications error for an output (1 to 4) specified by the instance ID. The setting can be read for a specified number of points. 1 byte 00 hex: Clear 01 hex: Hold 09 hex 01 to 04 hex 05 hex 1 byte 00 hex: Clear 01 hex: Hold Note The default setting is for all outputs to be cleared (0).
