1. Canatal Satchnet Protocol Driver Description

The Canatal Satchnet Protocol Driver allows the FieldServer to transfer data to and from devices
over either RS-232 or RS-485 using Canatal Satchnet Protocol Driver protocol. The FieldServer
can emulate either a Server or Client.

This driver provides support for the Canatal Corporation implementation of the “Satchwell
Network” protocol.

The Canatal Satchnet Protocol Driver can act as a Master.

• Any Satchnet device on any serial port (P1-P8, R1 & R2 on the FS-B40 Series, serial port

on the FS-B20 series) can be polled.

• Data from Series 2, 4, 5, 6, 9 devices can be polled.

• Data from any 'Table' can be read.

• Data in 'Tables' with write permission can be written by the driver.

• The dr iver can read/write Bit, Byte, Swapped Integer, Word, BCD and Float Data.

The Canatal Satchnet Protocol Driver can act as a (passive) server.

• The driver can be polled by a Satchnet Master and return data from the FieldServer's data

arrays.

• The driver can emulate Series 2,4,5,6,9 devices.

• All 'Tables' can be read / written.

CANATAL

Canatal Corporation Inc. have specified the following data with respect to
interconnecting cables.

Interconnecting Cable Characteristics

The interconnecting cable may be composed of twisted or untwisted pair (flat cable)
possessing the characteristics below. Conductor Size: The interconnecting cable shall be
composed of two wires of a 24 AWG or larger conduc tor for solid or stranded copper
wires, or for non-copper conductors with sufficient size to yield a DC wire resistance not
to exceed 30 ohms per 1000 feet per conductor.

• Mutual Pair Capacitance: The capacitance between one wire in the pair to the

other wire shall not exceed 20 picofarads per foot and the value shall be
reasonably uniform over the length of the cable.

• Stray Capacitance: The capacitance between one wire in the cable to all others in

the cable sheath, with all others connected to ground shall not exceed 40
picofarads per foot and shall be reasonably uniform over the length of the cable.

• Pair-to-Pair Balanced Crosstalk: The balanced crosstalk from one pair of wire to

any other pair in the same cable sheath shall have a minimum value of 40
decibels of attenuation measured at 150 kilohertz.

•

An interconnecting cable meeting these specifications will result in a transmission line
with a nominal characteristic impedance in the order of 100 ohms to frequencies greater
than 100 kilohertz and a DC series loop resistance not exceeding 240 ohms.

4. Configuring the FieldServer as a Canatal Satchnet Protocol Driver Client

For a detailed discussion on FieldServer configuration, please refer to the Configuration Manual for
the FieldServer. The information that follows describes how to expand upon the factory defaults
provided in the configuration files included with the FieldServer (See “.csv” files on the driver
diskette).

This section documents and describes the parameters necessary for configuring the FieldServer as a
master, configured to communicate with a Canatal Satchnet Protocol Driver Server ( a passive
Canatal device).

The configuration file tells the FieldServer about its interfaces, and the routing of data required. In
order to enable the FieldServer for Canatal Satchnet Protocol Driver communications, the driver
independent FieldServer buffers need to be declared in the “Data Arrays” section, the destination
device addresses need to be declared in the “Client Side Nodes” section, and the data required from
the servers needs to be mapped in the “Client Side Map Descriptors” section. Details on how to do
this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

4.1 Data Arrays

Section Title

Data_Arrays

Column Title Function Legal Values

Data_Array_Name Provide name for Data Array Up to 15 alphanumeric

characters

Data_Format Provide data format. Each data array can only

take on one format.

Data_Array_Length Number of Data Objects. Must be larger than

the data storage area required for the data
being placed in this array.

Example

// Data Arrays
//
Data_Arrays
Data_Array_Name, Data_Format, Data_Array_Length
DA_AI_01, UInt16, 200
DA_AO_01, UInt16, 200
DA_DI_01, Bit, 200
DA_DO_01, Bit, 200

FLOAT, BIT, UInt16, SInt16,
Packed_Bit, Byte,
Packed_Byte, Swapped_Byte
1-10,000
