New : Link RS Master now available.
New : Link NG-Web now available.
Modifications
for the version 2.4.003
New
option RS485 Short timing in Master and Slave RS Link. Needed for fast Master like
PCD2.M480
Channel 6 supported in
Master and Slave RS Link.
Assembler
error with Fbox Virtual Slave. Fixed.
Modifications
for the version 2.4.100
Slave Link RS : Option RS/TCP removed. Option ASCII added.
CRC calculation restored
with old code (faster if DB < 3000). Code expanded in macro (no more FB).
Master and Slave can now be
used in the same Fupla file.
The Modbus Slave function
now supports several serial lines in the same PCD (not yet OK for Master).
Modifications
for the version 2.4.101
Link error
: invalid FB parameters. Fixed.
Modifications
for the version 2.4.102
FW
problem with Modbus TCP. New FW use 8 flags instead of 5. The
Do not use former versions
with Modbus/TCP !
Modifications
for the version 2.4.106
Send Integer, F6 : a Warning is now issued if more than 1 register is
specified. Only 1 register is sent with function F6.
Assembler
errors with Fbox S-Bus Gateway. Fixed.
Assembler errors with Fbox
SLink-IP and option Station=External or S-Bus config. Fixed.

Modifications
for the version 2.4.109
New SEND, RCV and Slave
Station Indirect Fboxes. Please read carefully all recommendations in the Help
file before to use these Fboxes.
Master : New Error code 36 for invalid
function (instead of <91>) or if Bin Fbox passes a function code for
numeric data or vice-versa.
New
Fboxes Master and Slave RS Adjustable (runtime adjustable baudrate and bits
settings). New Fbox to define baudrate and bits from inputs.
Error with Link IP on PG5
1.3 (IPSlot changed to IPChannel). Fixed.
Slave Link Fbox : The option Station = External did not work. Fixed.
Modifications
for the version 2.4.112
The use of the Gateway
S-Bus with the Slave function had several errors with floating point and 32
bits values. Fixed.
Modifications
for the version 2.4.113
New Fbox Slave Link IP with
adjustable Idle disconnect time. This version is
necessary if you encounter the problem of dead-locked IP module (it is actually
a problem of the FW on the IP-Module).
To avoid this problem, use new the Slave Link IP Fbox of this version and set
the Idle disconnect time to a higher value (e.g. 60 sec instead of 10 sec).
Modifications
for the version 2.4.114
Bit settings with 2 stop
bits added in Master and Slave RSxxx.
Modifications
for the version 2.4.115
Correction in Virtual Slave :
- The Write function 6 and 16 did not work correctly.
- Assembler error if channel was not = 1.
Modifications
for the version 2.4.200
In Master TCP the Station
can now be an IP address (no need to create a node for external systems).
Allows to place several Master Driver in the same PCD.
Channel is now a virtual channel in range 1..10 (not
anymore related to the channel of the HW configuration).
Support high baudrates 57600 and 115200 also as indirect settings.
Station indirect
- New Fbox with Stn output for better synchronization.
- Station change now abort all pending com's on TX/Rx
Fboxes.
- Station change is now made at cycle begin (at station Fbox)
Modifications
for the version 2.4.300
New Fbox Multicast with
priority on Multicast add (add 0).
New option in Master and Slave RSxxx : RTU Fast. Uses CSF for faster CRC calculation. Need new FW !
Modifications
for the version 2.5.002
Minimum version for PG5 1.4
The version 2.5.001 must be replaced by 2.5.002
Modifications
for the version 2.5.008
Assembler error with Fbox 'Master-Link RS Adj' and 'Slave Link RS Adj'
on PG5 1.3 and 1.4. Fixed.
Assembler error with Fbox Send/RCV indirect. Fixed.
Master and
Slave Link RSxxx : New option Channel 0 PGU
with auto recovering after used with PGU cable.
New Map Slave Fbox with Station option (Intern/Extern/S-Bus
Config). So the
Map Slave Fbox follows the Slave Application Fbox when changed in runtime.
The Slave
Application now supports registers up to 16383 when running in PCD2.M480 or
PCD3.
The support
of registers above 4095 needs at least PG5 1.3.
Access to
registers above 8191 needs at least the following firmwares :
-
PCD2.M480 $16
- PCD3 $03
Problem
with TCP Master and several slaves :
On PCD3,
it is not possible to make successive connections to several Slaves. It is a FW
restriction and no new FW are currently available. It may works
if the activation of the successive slaves is made slowly, one by one (e.g. one
each 10 sec).
On all
systems, when a Slave is not responding, the following connection to
another slave may fail.
This last
point is now fixed with the Modbus library 2.5.008 except for PCD3.
Modifications
for the version 2.5.009
The access
of 32 bits and floating point values did not anymore works in the version
2.5.008. This error is now fixed.
When register and Timer/Counter addresses are checked and converted, the
priority is now changed as follow :
1)
Floating
point offset
2)
32
bits offset
3)
Normal
register range (was checked first in former version)
This allows
to use offset below 16’535 (for systems which disallow Addresses > 10’000)
even when the valid registers range is up to 16’535.
In some
rare cases this can cause incompatibility with existing program.
Example :
Offset 4000 was ignored for register 4000 to 4095. now
the offset will apply.
Modifications
for the version 2.5.010-011-012
The
Function Map Slave now also accepts register addresses up to 16383.
Some assembler errors fixed.
Modifications for the version 2.5.013.
Don't
use this version anymore!
Avoid
warning at download on PCD4.M17x. The min FW version for Modbus TCP on
PCD4.M17x is 010.
Mobus RTU and ASCCI, Master and Slave now support the channels 1xx on modules
PCD3.F2xx with the restriction: Baudrates>9600 may not work properly.
Minumim FW version is $26.
New input Sasi on function Master and Slave Link RS Adj. It allows you to de-assign and
re-assign the port in runtime.
Modifications for the version 2.5.014.
Don't
use this version anymore!
Errors
fixed:
Diag errors
are endless counting on PCD3 systems.
Master+Slave
RS Link caused assembler error with baudrates > 9600.
Modifications for the version 2.5.015.
Don't
use this version anymore!
Errors
fixed:
With Slave
Link IP, the channel 9 was not accepted.
Assembler error with Master Link IP on PG5 1.3.
Modifications
for the version 2.5.018
The
following fatal bug has been found:
With Modbus
TCP and UDP, Master and Slave, no communication is working but the driver
doesn't show any error. The error exists in version 2.5.013 – 014 – 015 – 016.
Do not use these versions anymore. Please update to versions 2.5.200 or up.
Modifications
for the version 2.5.019
Slave : Writing to IO did write on Flag after bit 15. Fixed.
Slave : Writing to F and IO did take 16 bits per reg
in buffer instead of 32. Fixed.
Slave : F15 write F (or IO) did write 1 more than in
request. Fixed.
Do not use these versions anymore. Please update to versions 2.5.200 or up.
Modifications
for the version 2.5.020
Avoid wrong warning message on PCD4.M170.
Modifications
for the version 2.5.022
Link RS. SASI error was replaced by <4> after
