The STROBE signal should not be input together with the
PRG_RST, CYC_RST, STEP_RST or DO_RST signal.
Because the ACK signal is used in common, only the first
signal which is input becomes valid and all other signals
become invalid.
If a file other than the current file is selected, the program is
reset to step 1 and the values of variables are reset also.
* Program file name and register of it to program number, and assignment of bits
to external digital input signals:
To select an execution file (i.e., program selection), using digital input or
extension input signals, assignment of bits to the controller input signals is
necessary.
User parameter [U07]
[U07] Specify signal for EXTSELECT.
{Signal No.} (1 – )
{Bit length} (1 – 4)
= 1 4
Bits underlined = (Leading signal name in DIN command) (Bit length).
"Signal name in DIN command" signifies an input signal number assigned in a
program to run the internal sequence. (The signal name is predetermined in
the program and cannot be changed by the user.)
For the digital input signal, "signal name in DIN command" represents a
number in parentheses as shown on the right side of the signal name in Fig.
4.3.
(Leading signal name in DIN command):
Specify the leading number of input signals to be used.
(Allowable range: 1 ~ 8, 101 ~ 164)
(Bit length):
Specify the number of signals to be used. (Allowable range 1 ~ 4)
Set value underlined (ex.) = 1 4
This signifies that four (4) external digital input signals 1 ~ 4 are used.
