12. Communication Design Examples Set starting reference for Master to write in DTA: H4701 1 data to be written in DTA Set starting reference for Master to read from DTB: H1000: s 2 data to be read from DTB Set starting reference for Master to write in DTB: H1001 3 data to be written in DTB Auto mode Enable PLC LINK Program Description: z Registers D1480~D1481 in PLC correspond to communication parameters H4700~H4701 of DTA TC. When X0 = ON, PLC LINK will be enabled and the value of H4700~H4701 (present and target temperature) will be shown in D1480~D1481. z Register D1496 in PLC corresponds to communication parameter H4701 of DTA TC.
When X0 = ON, PLC LINK will be enabled and the value of H4701 can be determined by the content in D1496. z Status of DTA TC can be controlled by setting the value in D1496. (D1496 = K300, the target temperature will be 30°C.) z Registers D1512~ D1513 in PLC correspond to communication parameters H1000~H1001 of DTB TC. When X0 = ON, PLC LINK will be enabled and the value of H1000~ H1001 (present and target temperatures) will be shown in D1512~ D1513. z Registers D1528~D1530 in PLC correspond to communication parameters H1001~ H1003 of DTB series temperature controller. When X0 = ON, PLC LINK will be enabled and the value of H1001~ H1003 can be determined by the content in D1528~D1530.
z Target temperature of DTB can be specified by the value in D1528 (D1528 = K400, the target temperature will be 40°C.) z Upper/lower limit of temperature range of DTB can be specified by the value in D1529~1530. (D1529 = K500 and D1530 = K10, the upper limit will be 50°C and lower limit will be 1°C. z Station No. of Slave should be continuous and different from the station No. of Master. SA/SX/SC/SV/EH/EH2 series PLC can be Master. ES/EX/SS series can not be Master. z When X0 = ON, PLC LINK will be enabled. If enabling action is failed, M1350/M1351 will be OFF and X0 needs to be activated again.
