1. Introduction
1.1 Overview
The GC-1502 module has integrated 2 counter digital input channels,
which acquires digital signals in real-time and transmits them to the GCAN-
PLC coupler. This module can be used with any other GC Series IO module to
capture and process digital data in industrial automation or distributed control
systems.

2. Installation
This chapter will describe the installation method, wiring method,
meaning of the indicator and meaning of the interface of the GC-1502 module.
2.1 Module fixing
The installation method of GC-1502 module as shown in Figure 2.1 and a
flat-blade screwdriver is needed for auxiliary installation.
Figure 2.1 Installation of GC-1502 module
First install the GCAN-PLC on the guide rail and plug the GC-1502 along
GCAN-PLC's right side until the lock is stuck. When remove the GC-1502, the
user need to release the self-locking mechanism by pulling out the orange label.
The GC-1502 module needs to be used with GCAN-PLC-400/510 or GCAN-
8000/8100 series couplers, and can be powered directly through the coupler, so
there is no need for a separate additional power supply.
2.2 Wiring method
The power wiring as shown in figure 2.2. First, use a flat-blade
screwdriver to insert into the square hole, hold the top edge of the metal sheet
in the square hole, and press toward the hole. Then, insert the wire into the hole.
After plugging in, pull out the screwdriver and the wire can be firmly locked in
the hole.

Figure 2.3 GC-1502 module terminal definition
The wiring terminal block of GC-1502 module is shown in Figure 2.3. GC-
1502 contains 2 groups of pulse inputs, and can connect to 2 pulse signals at
most. The corresponding serial numbers and definitions of each indicator are
shown in Table 2.1

2.3 System statusindicator
GC-1502 module has no error indicator light. Please judge the status of
GC-1502 module by "IORUN" and "IOERR" indicator lights of the GCAN-
8000 series coupler. If the "IO ERR" indicator of the GCAN-8000 series
coupler is on, please check the installation of the module.
No.

Table 2.2
2.4 Method of use
The counter states of the -1502 module are all represented by 4 bytes, and
the total number of bytes is represented by the total number of 4 states, which
are channel 1, count, channel 2 count, channel 1 frequency and channel 2
respectively
For example, when GC-1502 module is connected to PLC-400, four states
can be used as four IO variables and represented by four UDINTs.
Channel1Cnt AT % I0.0: UDINT; Channel2Cnt AT % I4.0: UDINT;
GC-1502 user manual
Channel1Fre AT % I8.0: UDINT; Channel2Fre AT % I12.0: UDINT;
Gc-1502 has two counter channels, INPUT1 and GND1 for the first group,
INPUT2 and GND2 for the second group.
When the pins of RST1 and RST2 of gc-1502 are connected to the high
current, the corresponding counter channel's count value and frequency can be
cleared.
2.5 Combined with GCAN- 8000series
The state of the digital input is represented by two byte
For example: the GCAN-IO-8000 module node number is 1, the channel 1 of
the first GC-1502 module count 28685, and the frequency is 56849Hz, then the
CAN data frame ID sent by the GCAN-IO-8000 module is 0x181, and the data
length ( DLC) is 8. The frame data is 0x0D, 0x70, 0x00, 0x00, 0x11, 0xDE,
0x00, 0x00. The following table lists a common counter status and its
corresponding status data.
