5.5.2  Read Coil Status (Function Code 01) 

Query 

This function allows the user to obtain the ON/OFF status of logic coils used to 
control discrete outputs from the addressed Server only. Broadcast mode is not 
supported with this function code. In addition to the Server address and function 
fields, the message requires that the information field contain the initial coil 
address to be read (Starting Address) and the number of locations that will be 
interrogated to obtain status data. 
The addressing allows up to 2000 coils to be obtained at each request; however, 
the specific Server device may have restrictions that lower the maximum 
quantity. The coils are numbered from zero; (coil number 1 = zero, coil number 2 
= one, coil number 3 = two, and so on). 
The following table is a sample read output status request to read coils 0020 to 
0056 from Server device number 11.

Response 

An example response to Read Coil Status is as shown in Figure C2. The data is 
packed one bit for each coil. The response includes the Server address, function 
code, quantity of data characters, the data characters, and error checking. Data 
will be packed with one bit for each coil (1 = ON, 0 = OFF). The low order bit of 
the first character contains the addressed coil, and the remainder follow. For coil 
quantities that are not even multiples of eight, the last characters will be filled in 
with zeros at high order end. The quantity of data characters is always specified 
as quantity of RTU characters, that is, the number is the same whether RTU or 
ASCII is used. 
Because the Server interface device is serviced at the end of a controller's scan, 
data will reflect coil status at the end of the scan. Some Servers will limit the 
quantity of coils provided each scan; thus, for large coil quantities, multiple PC 
transactions must be made using coil status from sequential scans.
