Version: 2.71
Details:
Serial/Ethernet Exploit to Retrieve PLC Password
If an attacker has access to the PLC, a specially crafted packet can be sent to the PLC via
Ethernet or Serial port to access the password. This could allow the attacker to use the password to retrieve
and/or make unauthorized changes to the project or interrupt the process.
Version: V2.70
Details:
This firmware version was created to support the D2-260 CPU modules with date code 1118 or newer that our vendor started using a new component in them. This new firmware works with any D2-260 CPU modules, but it is not necessary to install this firmware into the D2-260 CPU modules with date code 10Z8 or older because there is no difference in the functionality.
Version: V2.60
Details:
[New features]
- The following new modules are supported.
F2-16TD1P
F2-16TD2P
[Fixed problems]
- The override function did not work when the manaual addressing was used.
- With the PID control, the bias was reset to zero when the PID mode was changed from Manual to Auto. This problem occurred when the output value was high.
Version: V2.50
Details:
[Fixed problems]
- Pointer method for analog modules in the expansion bases did not work with certain setups.
Version: V2.40
Details:
[New features]
- This version supports IBox instructions. You also need DirectSOFT version 5 or later to use IBox instructions.
Version: V2.20
Details:
[New features]
- The following new modules are supported.
F2-8AD4DA-1
F2-8AD4DA-2
[Fixed problems]
- After the DirectNet master module requested diagnostic information through Port 1 of the D2-260, the D2-260 locked up.
- The response of Port 1 as a DirectNet slave was slow.
Version: V2.10
Details:
[Fixed problems]
- The STRPD instruction worked incorrectly after RUN time editing.
- The complete bit for the PRINT instruction did not work correctly.
Version: V1.90
Details:
[Fixed problems]
- JMP instruction did not work correctly.
- The D2-260 lost communication when run-time edit was executed while High speed I/O mode 40 (interrupts) was used.
- Output started flickering when firmware was updated while High speed I/O mode 40 (interrupts) was used.
- The D2-260 could not recognize the input signals for X0-X3 in the first scan.
Version: V1.80
Details:
[Fixed problems]
- SP36 (Override setup relay) did not work at all.
- Default retentive V-memory range started from V1400 instead of V400.
- The D2-260 could not execute the STRPD and STRND as the D2-250 did.
- The D2-260 could not execute a trapezoidal profile made for the D2-250 in mode 30.
- The velocity control in mode 30 did not work correctly when the CPU scan time was short.
- The Ramp/Soak for PID control did not work correctly if the independent format mode is selected.
- The PID output was not correct when the independent format mode is selected and the PID mode was changed from manual to auto.
- Ramp/Soak restarted automatically after power cycle.
Version: V1.70
Details:
[New features]
- The firmware version in the D2-CM can be read.
[Fixed problems]
- Several outputs in the expansion base were turned on after a short power drop no matter what the PLC mode was.
Version: V1.60
Details:
[Fixed problem]
- The TMR instruction did not work correctly in stage.
- When a stage is reset with a RST instruction, outputs turned on in the stage stayed on after the stage went off.
- Override stage bit did not work correctly.
Version: V1.52
Details:
Caution!
This firmware V1.52 has a safety problem with stage instructions. If you are using stage instructions in your program, please update your D2-260 with firmware V1.60 or later. If your D2-260 has firmware V1.40 or earlier, the D2-260 does not have the safety problem.
[Fixed problems]
- After a stage jumps to two or more stages at the same time, the outputs in the stage stay on even though the stage is off. (Only V1.50 has this problem.)
- When the first preset value was 1, high speed I/O mode 20 did not work correctly.
- The STRPD instruction did not work correctly if it was used in a stage with the stage number.
- Communication Port 2 could not communicate with a touch panel correctly in DirectNet.
- The automatic acceleration/deceleration trapezoid profile in high speed I/O mode 30 did not work correctly.
- The OROUT instruction did not work correctly.
- When a stage was activated with a SET instruction, outputs turned on in the stage stayed on after the stage went off.
Version: V1.50
Details:
Caution!
This firmware V1.50 has a safety problem with stage instructions. If you are using stage instructions in your program, please update your D2-260 with firmware V1.60 or later. If your D2-260 has firmware V1.40 or earlier, the D2-260 does not have the safety problem.
[New features]
- Power-up in RUN is supported. Turn on Bit 13 in V-memory V7633. This feature works only when PLC mode switch is in TERM position. This feature is disabled as the default.
- The firmware version is stored in V7727. For instance, if the firmware version is V1.50, V7727 has 1500.
[Fixed problems]
- Mode 30 did not work as fast as the D2-240.
- When the D2-260 without battery had not been powered on for a while, the memory had random data.
- Port 1 locked up during K-sequence communication.
- Port 2 replied to the master even though the protocol was not matched.
- Comm ports could communicate with peripherals only when the PLC mode switch was in TERM position.
- S option for VPRINT instruction did not work correctly.
- MWX/MRX instructions did not work correctly with more than 123 words.
- PID mode could not be changed in the first scan.
- Broken bits for the F2-04RTD in the expansion base did not work.
- 8 channel analog input modules did not work correctly in the expansion bases.
