1. Introduction
CB-7000 is a family of network data acquisition and
control modules. They provide analog-to-digital, digital-to-analog,
digital input/output, timer/counters and other functions. These
modules can be remotely controlled by a set of commands. The
DIO modules support TTL signals, photo-isolated digital inputs,
relay contact outputs, solid-state relay outputs, PhotoMOS outputs,
and open-collector outputs. Refer to Sec. 1.3 for detailed information.

2. Commands
Command Format: (Leading)(Address)(Command)[CHK](cr)
Response Format: (Leading)(Address)(Data)[CHK](cr)
[CHK] 2-character checksum
(cr) end-of-Command character , character return(0x0D)
Calculate Checksum:
1. Calculate ASCII sum of all characters of command (or re-
sponse) string except the carriage return (cr).
2. Mask the sum of string with 0ffh.
Example:
Command string: $012(cr)
Sum of string = ‘$’+‘0’+‘1’+‘2’ = 24h+30h+31h+32h = B7h
The checksum is B7h, and [CHK] = “B7”
Command string with checksum: $012B7(cr)
Response string: !01400600(cr)
Sum of string: ‘!’+‘0’+‘1’+‘4’+‘0’+‘0’+‘6’+‘0’+‘0’
= 21h+30h+31h+34h+30h+30h+36h+30h+30h = 1ACh
The checksum is ACh, and [CHK] = “AC”
Response string with checksum: !01400600AC(cr)

CB-7000 DIO Manual
3. Application Notes
3.1 INIT* pin Operation
Each CB-7000 module has a build-in EEPROM to store
configuration information such as address, type, baud rate and other
information. Sometimes, a user may forget the configuration of the
module. Therefore, the CB-7000 have a special mode named “INIT
mode”, to help user to resolve the problem. The “INIT mode” is
setting as Address=00, baud rate=9600bps, no checksum
T o enable INIT mode, please follow these steps:
Step 1. Power-down the module.
Step 2. Connect the INIT* pin to the GND pin.
Step 3. Power-up the module.
Step 4. Send Command $002(cr) in 9600 bps to read the
configuration stored in the module’ s EEPROM.
Refer to “7000 Bus Converter User Manual” Sec. 5.1
and “Getting Started” for more information.
3.2 Module Status
PowerOn Reset or Module Watchdog Reset will set all
outputs to the PowerOn Value. The module can accept the host’s
Command to change the output value.
Host Watchdog Timeout will set all output to the Safe
Value.The module’ s status (read by Command ~AA0) will be 04,
and the output Command will be ignored.
CB-7000 DIO Manual
57
3.3 Dual Watchdog Operation
Dual Watchdog = Module Watchdog + Host Watchdog
The Module Watchdog is a hardware reset circuit that
monitors the module’ s operating status. When working in harsh or
noisy environment, the module may go down by a noise signal. The
Module Watchdog times out and sets output to PowerOn value.
The Host Watchdog is a software function to monitor the
host’ s operating status. Its purpose is to detect a network communication problem or a halted host. When the timeout interval expired,
the module will put all outputs to the predefined Safe Value. This
places the controlled element in a known-safe condition.
The CB-7000 module with Dual Watchdog makes the
control system more reliable and stable.
3.4 Reset Status
The Reset Status is set while the module power on or reset
by Module Watchdog, and is cleared when the Command read
Reset Status ($AA5) is applied. This is useful for user to check the
module’s working status. When the Reset Status is set means the
module is reset and the output may be changed to the PowerOn
Value. When the Reset Status is clear means the module is not
reset, and the output cannot be changed.
3.5 Digital Output
A module’ s output can have one of three values:
1. Safe Value. If the host watchdog timeout status is set,
the output is set to Safe Value.If the module receives an output
58
CB-7000 DIO Manual
Command, such as @AA(Data) or #AABBDD, the module
ignores the command and returns ‘!’, and will not change the output to the output command value. The host watchdog timeout
status is set and stored in EEPROM when the host watchdog
timeout interval expired, and only can be cleared by Command
~AA1. If user wants to change the output, he first needs to clear the
host watchdog timeout status, then send an output command to
change the output to a desired value.
2. PowerOn Value. When the Module W atchdog T imer is
set, and the host watchdog timeout status is clear, the module’s
output is set to the predefined PowerOn Value.
3. Output Command value. If the host watchdog timeout
status is clear, the user issues a digital output command such as
@AA(Data) or #AABBDD to the module for changing the output
value. The module will respond successful (receive >).
3.6 Latched Digital Inputs
If, for example, the user connects a PB switch to a a digital
I/O module input channel and wants to read the switch stoke. The
input is a pulse digial input, and user will lose the data. When read
by Command $AA6 in A or B position, the re-
sponse is that no input occurred and he will lose
the pulse information. However, the read latch-low digital input
Command $AAL0 will solve this problem. When $AAL0 Command in A and B position is issued, the response indicates that there
was a low pulse between A and B position for a switch closure.

4.5 Application
The DN Modules are the IO extension of CB-7000 modules. These modules can drive more power and heavy loads . User
may use CB-7000 modules, like CB-7043 or
others, to control the DN modules to drive loads.
