Scanner 3100 Modbus Protocol Section 1

Section 1—32-Bit Modbus Protocol (Default)

Introduction

The communications protocol for the Scanner 3100 is in accordance with Modicon, Inc. RTU Mode Modbus as de­scribed in Modicon Modbus Protocol Reference Guide, PI-MBUS-300 Rev. J, June 1996. All registers are implemented as 4X or holding registers. Reading of registers is implemented via function code 03H (Read Holding Registers). Writing to registers is implemented via function code 10H (Preset Multiple Registers). The instrument provides Enron Modbus compliant downloads for interval, daily and event records. For details on Enron Modbus, refer to Specications and Re- quirements for an Electronic Flow Measurement Remote Terminal Unit for Enron Corp., Dec. 5, 1994.

Scanner 3100 Modbus Maps

Scanner 3100 protocol is supported by three pre-dened register maps and a Cameron software application, ScanMap,
for customizing maps to suit individual host requirements.
• Two Modbus maps are preloaded in the Scanner 3100:
– A 32-bit Enron Modbus map includes registers for the Scanner 3100 and up to 20 slave devices. These registers
are described in this section. This map is also stored in ScanMap software (see Table 1.1).
– A 16-bit Modbus map includes registers for the Scanner 3100 and up to 20 slave devices and presents values
in a 16-bit standard Modbus format. These registers are described in Section 2—16-Bit Modbus Protocol. This map is also stored in the ScanMap software (see Table 1.1 below).
• A third Modbus map—a version of the 32-bit Enron Modbus map without slave device registers (“base unit” map)—is
available for download from Cameron’s ScanMap software. See S3100_MAP_TEMPLATE_ ENRON_BASE_UNIT
in Table 1.1. See ScanMap Download below for download instructions.

User-Dened Maps (ScanMap Software)
ScanMap software allows a user to create a custom Modbus register map by modifying the contents of a pre-dened map or using a blank template and selecting individual registers. ScanMap includes databases for all three of the pre-dened Modbus maps described above. Each can be used as-is, or modied with user-specied registers and units.
See Table 1.1 for the names of available register map templates.

Section 1 Scanner 3100 Modbus Protocol

Standard Modbus Functions

The Modbus functions supported by the Scanner 3100 are as follows:
Function Code (Hex) Description
03 Read Holding Registers
10 Preset Multiple Registers

Data Types

Various data types are implemented in the Scanner 3100. The following table lists the formats and the numbers of bytes and registers associated with each type.
Data Format Data Type Byte Count Register Count
32-bit Floating Point (FP) 4 1
Unsigned Long (INT32) 4 1
Packed ASCII (String [4]) 4 1
16-bit Floating Point (FP) 4 2
Unsigned Long (INT32) 4 2
Packed ASCII (String [4]) 4 2
Enron Record (ER) — —
The word ordering for multiple register data types, such as oating-point numbers or long integers, is for the most signif­icant word to appear rst in the message.

Packed ASCII

The Packed ASCII (PA) type contains four bytes that are four unsigned characters. Generally, multiple Packed ASCII types are arranged consecutively for implementing strings. For example, the Model Number is a string of 16 unsigned characters that is implemented as four Packed ASCII registers. Here is an example of a model number from the 32-bit in­ternal Enron Modbus map that contains the string “S3100-G1.”
Register Hexadecimal ASCII Characters
105 53 33 31 30 S310
106 30 2d 47 31 0-G1
107 00 00 00 00 <UNUSED>
108 00 00 00 00 <UNUSED>
Unused characters at the end of each string will report 0x00 hexadecimal.

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 (RW) Register Can Be Read and Written
The registers are grouped into Modbus map blocks according to function. The Scanner 3100 contains the following map functions.

– Flow Run 1: Calibration: Nominal Factor, Address 8318
– Flow Run 2: Calibration: Nominal Factor, Address 8418

2. Write the Command Arguments 1 through 4 (Address 71-74) to choose the input to be updated.
3. Write the code for Command Register (Address 75) in unsigned long format. The code is 600300 for ow runs and 600302 for pulse inputs.

Model Number
The Model Number is a read-only parameter set by the factory, stored in two 32-bit registers and used to identify a Scan­ner 3100 device. See Packed ASCII, page 8, for details about decoding packed ASCII values.
Firmware Version
Firmware version numbers are read-only values set by the factory and stored in the IEEE 754 single precision oating point format. For example, a rmware register number is read as 0x3F853F7D in hexadecimal. This represents a version as 1.041.
Manufacture Date/Sales Date
These date and time parameters are read-only values set at the factory and stored in the IEEE 754 single precision oating point format in two 32-bit registers. Only the integer portion of the oating point value is used to represent the date or time. The rst register denes the date in MMDDYY format. The second register denes the time in HHMMSS format.

Generally, the Scanner 3100 low, high, low-low, and high-high conditions for inputs are dened as shown in the follow­ing table.
Status Description
Low Below transducer range by 0.5% of span
Low Low Below transducer range by 20% of span
High Above transducer range by any amount
High High Above transducer range by 20% of span
Alarm records are created when the device goes into and out of alarm condition. For example, an alarm is created when a damped input is greater than the upper end of the transducer range. The alarm will not clear until the damped value is
less than 0.5% of span below the upper limit of the transducer range. A damped value is altered by eld calibration but
has not been altered by the low input cutoff value.
Fail status results when any of the following fail conditions exist.
Input Fail Condition
RTD Open circuit or short circuit is detected
1 to 5 VDC Input less than 125 mV
4 to 20 mA Input less than 0.5 mA

Digital Output Status

Digital Output: Holding: Output
Digital Output: Holding: Output registers report the state of the corresponding digital output when Digital Input/Output mode is congured as one of the following settings:
• Alarm. Selected device alarms.
• Conditional. Value above setpoint, value below setpoint, or value out of setpoint range.
• Programmed. Time of day output control or controlled output state (via serial port).
Read the corresponding register to determine its output state.
Value Output Status
0 Disabled
1 Enabled
Digital Output: Holding: Pulses
Digital Output: Holding: Pulses registers can be used to set the Digital Output state when the Digital Input/Output mode is congured as “Programmed–Controlled Output State (via serial port).”
Value Output Status
0 Disabled
Any other integer Enabled
Write a value to the desired Digital Output: Holding: Pulses register to set the output state. Read the corresponding Hold­ing: Output register to validate the digital output status.
