3. Data View Instructions for the DL305 aT Special Data View Instructions for DL305 Family DirectNET Restrictions Unlike the DL105 DL205 and DL405 PLC families the DL305 family can only use DirectNET protocol This protocol allows you to READ the status of each internal relay directly but it will not allow you to use the Data View window to change the status of an internal relay by WRITING to that bit individually Instead you must do so indirectly by addressing the respective status register that includes the bit whose status you wish to change Using the example introduced on Page 6 of this manual C 160 was designated as the Start Switch If you refer to the memory map for the DL3805 you would find that C160 is the first bit of status register R16 Consequently in order to change the status of the Start Switch via the Data View window you must write an 8 bit word to R16 making sure the first bit is flagged You can start by first entering the element R16 in the Data View window When moving the cursor to click another field you will notice the alias RC160 appears in place of R16 Do not confuse this alias with C160 The RC designation refers to the entire 8 bit register R16 but C160 refers only to the first bit The number shown in the status column by default is in BCD hex format Ete Eat Beon wiee Tails ELG Dateg Barwin iep ror ae grit in 7 R nET CE Gai Ari E Yew ou E ee aut ir 7 z ae i alr jE H I When you mo
