(3) Trigger conversion signal assignment
Assign Trigger conversion request (RY19) of the main A/D converter module to Remote input (RX) of the
extension input module by using the external signal assignment function. Turning on the assigned Remote input
(RX) from off allows A/D conversion to be performed through the trigger conversion function.
(a) Setting range
With the head of Remote input (RX) of the main A/D converter module as a starting point (0000H), set the
number, which is counted from the head, of Remote input (RX) of the extension input module.
Ex.
When Trigger conversion request (RY19) is assigned to Remote input (RX) numbered 8H as counted
from the head (0H) of the extension input module
Remote input (RX) numbered 8H as counted from the head of the extension input module corresponds to
Remote input (RX) numbered 28H as counted from the head of the main A/D converter module.
Thus, set 28H for Trigger conversion signal assignment (address: 0002H).
(b) Enabling the setting
Turn on and off Initial data setting request flag (RY9) to enable the setting.
(c) Default value
The default value is No assignment (FFFFH).
(d) Remote buffer memory address
The remote buffer memory address of this area is as follows:
Remote buffer memory name
Trigger conversion signal assignment
● Setting a value out of the range results in the error code (0170H) being stored in Latest error code (RWr0), Error flag
(RXA) turning on, and the ERR. LED lighting up. with the previously set operation.
● With Trigger conversion signal assignment (address: 0002H) set to Remote input (RX) of the extension input module,
turning on Trigger conversion request (RY19) of the main A/D converter module from off does not allow A/D conversion.
Turn on Remote input (RX), which is set in Trigger conversion signal assignment (address: 0002H), from off.
