Data Map: Level Products Applicaton Layer Note: The data maps shown for the Write and Read Blocks apply if P762 is set to the default values (see page 15). If any of these values is changed, the data map will be shortened and the configuration will change. (See Appendix A – Reducing the amount of data being transferred over the Bus, on page 46.) This section describes the meaning of the data read from and written to the Siemens Milltronics SmartLinx instrument. Write Block Word 0: Point-on-Priority Bits 00-09 set the priority status of corresponding indexed points 1 to 10.
bit status 0 = normal 1 = priority For example, if bits 00 and 02 are set to 1, then points 3 and 1 are on priority scan. All other bits are reserved and contain 0.
