09/30/2016

F. Englert

•The Block Tag for receiving SD, DC, and RC Commands from this Driver in Slave IEC 870-5-101 mode and IEC 870-5-104 now returns an array of Variants instead of an array of integers, allowing the manipulation in scripts of an application (Case 21588).

•Fixed a GPF that occurred in this Driver in Slave mode of protocols IEC 870-5-104 or IEC 870-5-101 Balanced right after responding a General Interrogation (Case 17643, caused on v2.22.50).

2.22.50

10/23/2014

2.22.32

02/08/2011

F. Englert

•This Driver, both in Master and in Slave mode, now forces a disconnection if they do not receive a TESTDTcon as a response to a TESTDT act (Case 12043).

2.22.23

08/18/2009

F. Englert

•When the number of octets of a Cause of Transmission was 2 (two), this Driver considered the second octet a part of that Cause of Transmission, but in fact that octet is the Originator Address. Now, this Driver discards the Originator Address in the received packets. When transmitting, this Driver always sends 0 (zero) in the Originator Address (Case 10723).

2.22.19

05/19/2009

2.22.16

03/12/2008

F. Englert

•This Driver in Master mode now returns automatically a General Interrogation if it receives and indication of General Interrogation ending, that is, cot equal to 10, there is no active General Interrogation, and the last General Interrogation failed (Case 9260).

2.22.15

03/10/2008

F. Englert

•Implemented a new Stations tab on this Driver's configuration window. This tab allows users to configure whether this Driver creates Stations automatically, the old mode, or restricts communication to user-declared Stations, the new mode (Case 7687).

•Now this Driver in Master mode of protocol IEC 870-5-104 uses the Wait M_EI_NA on activation option to control the behavior when waiting for STARTDT.CON (Case 8963).

2.22.12

06/19/2007

F. Englert

•Fixed the handling of FCB bit, which was incremented before knowing whether a packet was successfully sent or not (Case 8405).

•Fixed the handling of Read Interrogation Group Commands in this Driver in Slave mode (Case 8406).

•Implemented a discard of invalid messages. If a RESPOND_NACK is received as a response to a SEND/CONFIRM, it is discarded and this Driver keeps waiting for a CONFIRM_ACK or CONFIRM_NACK (Case 8151).

•Added a new option on the Commands tab to allow waiting or not by an ACTTEM from General Interrogation, Wait ACTTERM (Case 8401).

2.22.11

04/13/2007

F. Englert

2.22.10

04/13/2007

F. Englert

•Fixed the behavior of this Driver in Slave mode, which was ignoring the quality of received data from an application and sending to the Master always with a Good quality (Case 8111).

•Added a new Tag N2 equal to 6 (six) in this Driver in Slave mode, which allows spontaneously sending data with Class 1 (one) and also in General Interrogation, if configured (Case 7653).

2.22.8

03/23/2007

F. Englert

•Fixed the behavior of timer T2 in protocol IEC 870-5-104, which could lead this Driver to exceed the maximum time for sending an ACK packet, that is, 10 seconds (Case 8038).

2.22.7

03/06/2007

F. Englert

•Fixed the format of parameter N2 equal to 99, which was returning a date in Double format from Elipse SCADA (Case 7954).

•Added to the Commands tab a list that allows selecting the way this Driver in Slave mode handles Select and Execute Commands, default (pass to application) (Case 5963).

2.22.6

02/16/2007

2.22.3

01/10/2007

F. Englert

•This Driver is now protected by ID 31290 (Case 7797).

•Now quality changes to 216 when generating a timestamp. This only occurs if quality before was Good (192). If quality's value was any value different from 192, it does not change (Case 6569).

2.22.1

09/28/2006

F. Englert

•Fixed the handling of double points received with an invalid value, 00b or 11b, which were discarded if configured to handle double points as a Boolean value (Case 7423).

08/18/2006

F. Englert

2.20.1

08/11/2006

F. Englert

•Fixed the example script for handling Commands received by a Slave, which did not work (Case 5452).

•Now the log registers events discarded when the internal cache memory is full, that is, more than 100 events for a single object (Case 6563).

•Fixed an incorrect timestamp (zero) sent when using data types from protocol IEC 870-5-104 in Slave mode (Case 6564).

•Fixed the Slave polling rate parameter, which has no effect when communicating with a Slave (Case 6570).

•Fixed the receiving of data with a timestamp marked as invalid (IV equal to one), and data itself was marked as invalid and only the timestamp should be discarded (Case 6666).

•Master and Slave modes were extensively tested and performed small improvements (Case 6798).

•Fixed the usage of a fixed one-second time-out, instead of using the time configured in the App Layer Timeout option, when users must send a Command and the application layer is busy, such as when using a General Interrogation, leading to a Command failure (Case 6848).

•Fixed the timestamps sent or received, which could be incorrect with a one-millisecond difference when received or sent by an application. This fix only works together with E3 v2.5 Build 131 and IOKit v1.13 (Case 7256).

•Added support for Command ASDUs 48 (C_SE_NA_1), 49 (C_SE_NB_1), 50 (C_SE_NC_1), and 51 (C_BO_NA_1) (Case 5361).
