Caution
1 Since the power supply of ZM-1MD2 is supplied from CPU, pay attention to capacity of 5V power supply
of CPU.
2 For wiring, it is fully careful to a noise.
3 There is the following restriction when ZM-1MD2 is used for QnA series CPU port.
1. When using it in ZM40/61 series, re-try time is 3 seconds.
The communication time out is 20 seconds between GPP and CPU.When any communication error
occurs between GPP and CPU, ZM-1MD2 maintains 20 seconds as communication time between
GPP and CPU.
After passing 20 seconds, although a communication port is changed to ZM between CPUs, since it is
3 seconds, the re-try time of ZM-40/60 series serves as a time-out, and a communication error occurs.
Perform re-execution 20 seconds after.
2. When you use it in ZM-41/70/80 series, choose from the two following methods.
- With the [Detail Setting] menu of the [Communication Parameter] of a [System Setup], [Communication
error processing] is set as "Continuation."
- [Time-out time]x [re-try time] may become more than 20 seconds.
3. Write in running
When the write-in operation in running is performed from GPP side and the time required is larger than
20 seconds, ZM-1MD2 cannot be used. In this case, written in STOP state for PC.
In addition, although the number of steps of the program which can perform writing among RUN in
less than 20 seconds has a difference according to the contents of a program, it is computable in the
following formula as a standard.
Time = (Number of steps ÷ 60) × scan time (msec)
A standard is asked in this formula. In addition, in the case of constant scan, this formula cannot apply.
4. When a power supply is switched on where a console is connected to the ZM-1MD2, a console will
become a communication time-out before completing initialization of the ZM-1MD2.
When it connects again or reset operation of a console is performed once it, removes the cable of a
console, it will return to a normal state. (Normal operation of this machine is carried out after 15 seconds
progress from the time of a power supply injection.)
4 When you use ZM-1MD2 for A series/FX series CPU, set time-out time as 1.5 seconds or more by commu
-nication parameter setup of ZM41/70/80.
