User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
Output list submenu
This submenu allows the user to edit the output channels registers to be written. When at
least one Output Channel is added to the list, then an Output channel menu is displayed.
The parameters of the Output channels are:
– Output active ,
•
no
– the output channel is defined but invisible in the
External output
menu
(see Chapter 7.11. EXTERNAL OUTPUTS ),
• yes – the output channel is defined and visible in the External output menu
(see Chapter 7.11. EXTERNAL OUTPUTS ).
– Control type
•
as a relay
- the output has two state, low state: value '0' and high state: maximal
value (for 16-bit format is the value 65535),
•
as a linear output
- can take any value depending of the settings in
Output register and settings the parameters in the External outputs menu
(see Chapter 7.11. EXTERNAL OUTPUTS ),
– Output register submenu - menu where user can set details of the Modbus register
to be written - see
Chapter 7.15.3.3. Modbus MASTER - Register settings
.
7.15.3.3. Modbus MASTER - Register settings
The submenu of registry settings in the Modbus protocol has the following fields:
– Register type – this parameter is only for the register settings in the Input list menu
(for the Output list menu the registers are HOLDING type), a user can select two
types:
•
HOLDING
- holding registers of SLAVE device compatible with Modbus protocol
• INPUT - input registers of SLAVE device compatible with Modbus protocol
– Write mode – read only parameter, informs about possibility to read or write register,
– Register number - any value from 0 to 65535
– Data format , we can select one of these options:
•
16 bits, signed
- integer value, the most significant bit is the sign bit,
•
16-bits, unsigned
- integer value without information about the sign,

• 32-bits, unsigned - integer value without information about the sign,
• 32 bits, float , floating point IEEE 754 format,
• 16-bits, BCD , unsigned BCD value, write two digits in each byte,
•
32-bits, BCD
, unsigned BCD value, write two digits in each byte,
–
32 bit reading
, this parameter is only for 32-bit format, user can select one of these
options:
•
two 16-bit registers ,
• one 32-bit register
– Ordering - this parameter is only for 32-bit formats, the letters ABCD means: A -
most significant byte of high words (word = 2 bytes), B - least significant byte of the
high words, C - most significant byte of low words, D - least significant byte of the low
words
• ABCD (standard)
• CDAB ,
• DCBA ,
• BADC ,
