Appendix C Scanner ® 2000 microEFM • Port SlaveAddress • Port BaudRate • Port BusDelay • Port BusTimeout • Real Date • Real Time Data Types Various data types are implemented in the Scanner 2000. The following table lists the formats and the numbers of bytes and registers associated with each type. C-2 Data Type Byte Count Register Count Floating Point (FP) 4 2 Floating Point (FP32) 4 1 Unsigned Word (U16) 2 1 Unsigned Long (U32) 4 2 Packed ASCII (PA) 2 1 The word ordering for multiple register data types, such as floating-point numbers or long integers, is for the most significant word to appear first in the message. The Unsigned Word (U16) type is used for 16-bit integers and fits into one register. The Packed ASCII (PA) type contains two bytes that are two unsigned characters. Generally, multiple Packed ASCII types are arranged consecutively for implementing strings. For example, the Device Name is a string of 20 unsigned characters that is implemented as 10 Packed ASCII registers. Here is an example of a device name that contains the string, “Test Well 413.” Register Hexadecimal # ASCII Characters 240 54 65 Te 241 73 74 st 242 20 57 W 243 65 6C el 244 6C 20 l 245 34 31 41 246 33 FF 3 247 FF FF 248 FF FF 249 FF FF Unused characters at the end of each string will report 0xFF hexadecimal.
Scanner ® 2000 microEFM Appendix C Security To communicate with a Scanner 2000 without the use of ModWorX Pro software (i.e. via a third-party polling device), security permissions for the applicable Scanner 2000 communications port must be set to the default (unrestricted) state. If a different security level is required, contact Cameron technical support for details. Security levels can be restored to default permissions with ModWorX Pro software. Registers Each register has an Access type: read-only or read-write, as described below. Access Type Description Read Only (RO) Register can only be read Read/Write (R/W) Register can be read and written The registers are grouped into Modbus® map blocks according to function. The Scanner 2000 contains the following map functions.
