FS-8700-64 ATMI ACM Page 2 of 22 1. ATMI ACM Description The ATMI ACM driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using ATMI ACM protocol. There are eight RS-232 and two RS-485 ports standard on the FieldServer. The FieldServer can emulate a passive client. ( A passive client is one that that consumes messages produced by an remote device.) 2. Driver Scope of Supply 2.1 Supplied by FieldServer for this driver FieldSe

FS-8700-64 ATMI ACM Page 4 of 22 4. Configuring the FieldServer as a ATMI ACM Client The ATMI ACM driver is a passive client driver. This means that it processes unsolicited incoming data. It cannot poll for data. For a detailed discussion on FieldServer configuration, please refer to the instruction 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 “.c

This example illustrates the map descriptors required to complete store ACM data for 80 areas. Each map descriptor tells the ATMI ACM driver where to store each component of ACM data. The gas number & area number determine the position in the array. Read section 6.1 for more information Map_blocks Map_block_Name, Data_Array_Name, Data_Array_Offset, Function, node_n

This example illustrates a map descriptors used to store the data from the most recent port sample. The map descriptor stores the following information :- 1. Port Number 2. Up to 16 gas values (The gas name is not provided) The position in the array is based on the Gas Number. For example. A port may sample two gasses. The first is Gas #4 and the second may be

When a malfunction is cleared then 100 st nd elements of the array are set to zero. When a Malfunction is present the 1 element contains the malfunction’s major type, the 2 element contains the minor type and element x (x=major*10+minor) is set to a value of 1.

FS-8700-64 ATMI ACM Page 13 of 22 6.2 Driver Stats The ATMI ACM Driver counts all incoming bytes as the ‘PLC Byte Received’ statistic. This can be viewed on the connection detail and overview screen. Typically this count will increase by approx 2500 bytes per full screen of area data. IN addition the driver reports one count of ‘PLC READ MSG RECD’ statistic for each map descriptor used to store information from a complete message. Typically this count will increase by 5 i

No map descriptors were found on the indicated port with which the driver could store the incoming data. Change the CSV file and reset the FieldServer. This message is only printed once even if the error occurs more than once. ATMI:#6 FYI. The mapDesc called <%s> is too short. Edit the CSV file. Increase the length of the map desc and reset the FieldServer. ATMI:#5 FYI.

Occasional timeouts may be expected when there are noisy messages or if the ACM device has been locked. Timeouts do not stop the driver processing the next valid screen of data. 6.6 Demand & Lock Scan The driver can process data from demand and locked scans. Incoming data is processed in the same way as normal scans and stored using the same map descriptors.

FS-8700-64 ATMI ACM Page 19 of 22 When you use a “…-alarm” keyword then the driver stores a 1 when the gas is in an alarm condition and a zero when it is not in alarm condition. This means a zero is stored even if the gas in a warning condition. When you use a “…-warning” keyword then the driver stores a 1 when the gas is in a warning condition and a zero when it is not in warning condition. This means a zero is stored even if the gas in an alarm condition as well as when the
