# 2017-04-21 optimize call to _send in GetUpdate, new attribute nonPrioritizedSet
|
||||
# remove unused variables for devInfo / parseInfo in ParseObj
|
||||
# 2017-05-08 better warning handler restore (see $oldSig)
|
||||
#
|
||||
# 2017-07-15 new attribute sortUpdate to sort the requests by their object address
|
||||
# new attribute brokenFC5 for misbehaving devices that don't understand the normal ff00 to set a coil to 1
|
||||
# set this attr e.g. to 0100 if the device wants 0100 instead of ff00
|
||||
# 2017-07-18 started implementing data types (3.6.0)
|
||||
# 2017-07-25 set saveAsModule
|
||||
# 2017-08-17 nicer logging of timeouts
|
||||
#
|
||||
#
|
||||
# ToDo / Ideas :
|
||||
# get reading key (type / adr)
|
||||
# filterEcho (wie in private post im Forum vorgeschlagen)
|
||||
# set saveAsModule to save attr definitions as module
|
||||
# define data types VT_R4 -> revregs, len2, unpack f> ...
|
||||
# async output for scan? table? with revregs etc.?
|
||||
# get object-interpretations h123 -> Alle Variationen mit revregs und bswap und unpacks ...
|
||||
# nonblocking disable attr für xp

if this file is copied into the fhem module subdirectory (e.g. /opt/fhem/FHEM) and fhem is restarted then instead of defining a device

as ModbusAttr with all the attributes to define objects, you can just define a device of the new type ModbusGen<name> and all the

defines an encoding to be used in a call to the perl function encode to convert the raw data string read from the device to a reading.

This can be used if the device delivers strings in an encoding like cp850 and after decoding it you want to reencode it to e.g. utf8.

If a device with many objects uses for example floating point values that span two swapped registers with the unpack code f>, then instead of specifying the -unpack, -revRegs, -len, -format and other attributes over and over again, you could define a data type with attributes that start with dev-type-VT_R4- and then

use this definition for each object as e.g. obj-h1234-type VT_R4<br>
